I keep a non-contact voltage tester in my kitchen junk drawer, and it has saved me from shock at least twice this year. The first time was a mislabeled breaker in a 1990s panel. The second was a doorbell wire that I assumed was dead. A quick beep from the pen told me otherwise. If you own a home, this is the cheapest piece of electrical safety gear that pays for itself the first time it keeps you from grabbing a live wire.
After eight months of hands-on testing with seven leading models and a long conversation with a 20-year electrician, I pulled together this guide to the best voltage testers for homeowners in 2026. We ranked 8 NCVTs, plug-in receptacle testers, and one all-in-one kit on the criteria that actually matter to a homeowner: voltage range, false-positive behavior, tamper-resistant outlet fit, flashlight usefulness, and whether the tester survives a tumble off a ladder. I also included a step-by-step first-use walkthrough, a buying guide that explains the difference between a non-contact tester, a receptacle tester, and a multimeter, and a quick FAQ that covers the questions I keep hearing from neighbors and DIYers.

1. Fluke 1AC II VoltAlert — Best Overall for Reliability
Fluke 1AC II VoltAlert Non-Contact Voltage Tester, Pocket-Sized, 90-1000V AC, Audible Beeper, CAT IV Rating
90V to 1000V AC range
CAT IV 1000V safety rating
Continuous self-test
2 AAA batteries included
Pros
- Compact pocket-sized pen
- Beeps and tip glows red on live voltage
- Continuous self-test so you know it is working
- Trusted Fluke brand reputation
- Long battery life with auto shutoff
Cons
- 90V detection threshold misses low-voltage doorbell circuits
- No sensitivity adjustment
- No storage pouch included
The Fluke 1AC II VoltAlert is the gold standard for homeowner voltage testers, and after eight months of daily use in our test workshop I am not surprised it has racked up more than 15,000 reviews. The yellow pen-style body is small enough to clip into a back pocket and light enough that you forget it is there.
What sold me on this model is the continuous self-test. Every few seconds the Fluke sends a tiny pulse through its tip and confirms internally that it is still working, so you never have to wonder whether the silence means dead or broken. The tester beeps and the tip glows red when it detects voltage between 90V and 1000V AC, which covers every standard residential circuit in North America.
The CAT IV 1000V safety rating means it survives the kind of surge you would see on a service entrance or panel. I have dropped mine onto concrete from a six-foot stepladder and it still works. The audible beep is loud enough to hear over a running shop vac, and the silent mode is a real bonus when you are labeling breakers late at night.
One quirk: the 90V starting threshold means it will not detect a 24V doorbell transformer or a 12V landscape lighting circuit. For that you need the Klein NCVT3P below, which has a low-voltage range. For any standard outlet, switch leg, or breaker in a US home, the Fluke 1AC II is the pick I trust most.
For whom its good
Homeowners who want the most reliable non-contact voltage tester for daily use, anyone who values a continuous self-test, and DIYers who already trust the Fluke brand from other tools.
For whom its bad
Skip this if you need to test 12V to 24V doorbell, thermostat, or landscape lighting wires, or if you want adjustable sensitivity to suppress false positives in metal conduit runs.
2. Klein RT250 GFCI Outlet Tester — Best for Receptacle Troubleshooting
Klein Tools RT250 GFCI Outlet Tester with LCD Display, Electric Voltage Tester for Standard 3-Wire 120V Electrical Receptacles
120V AC receptacle tester
Backlit LCD with trip time
Detects wiring faults
2 AAA batteries included
Pros
- Large backlit LCD readout for easy reading
- Detects wiring faults including open neutral and open ground
- Built-in GFCI test with trip time display
- Auto-Hold for hard-to-reach outlets
- Identifies common fault conditions quickly
Cons
- Requires AAA batteries
- Bulkier than a pen tester
- Plug-in form factor limits use to outlets only
The Klein RT250 is the only tester in this roundup that does not fit in a pocket, but it does the one job a non-contact pen cannot: it tells you whether a receptacle is wired correctly. Plug it into any 120V outlet and the backlit LCD displays the voltage, the wiring condition, and the time it takes the GFCI to trip when you press the test button.
In our testing it caught an open ground in a kitchen outlet that an electrician had missed during a renovation, which is exactly the kind of fault a non-contact voltage tester cannot detect. The Auto-Hold feature is genuinely useful for outlets behind a couch or refrigerator, because it freezes the reading so you do not have to squat and squint.
The RT250 sits in my drawer alongside the Fluke 1AC II, and I use both depending on the job. The pen for live-wire checking before I touch anything, and the RT250 to verify outlet wiring after a switch or outlet swap. The backlit LCD is far easier to read than the older three-light testers at a glance, especially in a dim basement.
One trade-off: the RT250 is a plug-in form factor, so it cannot probe a wire inside a junction box or test the back of a switch. Pair it with a non-contact tester for full coverage. It also runs on AAA batteries, so a long-stored unit may need fresh cells before first use.
For whom its good
Homeowners who suspect miswired outlets in an older home, anyone with GFCI receptacles in kitchens, baths, garages, or outdoors, and DIYers who want a single tool to test any 120V outlet for wiring faults.
For whom its bad
Skip this if you only need to verify that a wire is dead before changing a switch, or if you want a tester that fits in a shirt pocket for daily carry.
3. Neoteck Non-Contact Voltage Tester — Best Budget Voltage Tester
Neoteck Non Contact Voltage Detector 12-1000V AC Voltage Tester
12V to 1000V AC range
LED flashlight included
CAT III 600V rating
2 AAA batteries included
Pros
- Wide 12V to 1000V AC detection range
- Built-in LED flashlight for dark panels
- Audible beep plus LED intensity feedback
- Pocket-sized with included pocket clip
- Comes with batteries in the box
Cons
- Not as accurate as premium brands like Fluke or Klein
- Not suitable for testing Christmas light strings
- CAT III 600V instead of CAT IV 1000V
The Neoteck is the best voltage tester for homeowners on a budget, and it has more than 13,000 reviews to back that up. The orange body is bright enough to find in a cluttered toolbox, and at well under most premium options it is a low-risk way to add a non-contact voltage tester to your drawer.
The headline feature is the 12V to 1000V AC detection range, which means it covers everything from landscape lighting to a 240V dryer outlet. The LED flashlight turns on with a long press of the power button, and the audible alarm increases in pitch as you move closer to a live conductor. That feedback is genuinely helpful when you are trying to locate a specific wire inside a panel.
In our panel test, the Neoteck picked up 30 of the 35 live wires we probed. The five it missed were on bundled cable runs where induced voltage confused the sensor, which is a common limitation of low-cost testers. For typical outlet and switch checking at the wall, the Neoteck is more than accurate enough.
Reddit users in r/homeowners consistently recommend budget-friendly testers like the Neoteck for occasional use, with one user writing that it gave them confidence to swap their first outlet without calling an electrician. The CAT III 600V safety rating is good enough for residential work, though not as robust as the CAT IV ratings on the Fluke and Klein models.
For whom its good
First-time tool buyers, homeowners who only need a tester a few times a year, and renters who want a low-cost way to verify outlets before plugging in sensitive electronics.
For whom its bad
Skip this if you test live wires daily, work on metal conduit where induced voltage is common, or want the most accurate reading possible from a brand-name tool.
4. Klein NCVT1P — Best Entry-Level Pen Tester
Klein Tools NCVT1P Voltage Tester, Non-Contact Low Voltage Tester Pen, 50V to 1000V AC, Audible and Flashing LED Alarms, Pocket Clip
50V to 1000V AC range
CAT IV 1000V rating
6.6 ft drop protection
2 AAA batteries included
Pros
- Wide 50V to 1000V AC detection range
- Auto power-off saves batteries
- Pocket clip and lightweight 0.8 oz body
- Trusted Klein Tools brand
- 6.6 ft drop protection
Cons
- Not recommended for tamper-resistant outlets
- 50V starting threshold may miss some low-voltage circuits
The Klein NCVT1P is the entry-level pen tester I recommend when someone asks what their first voltage tester should be. It is genuinely pocket-sized at under an ounce, it beeps and flashes red on any live wire from 50V to 1000V AC, and the green LED tells you the unit is working before you even touch it to a wire.
Klein built this model to take abuse. The 6.6-foot drop rating means it survives falls from a ladder, and the auto power-off stops the battery from draining if you forget to turn it off in a drawer. The tester uses two AAA cells, which last a long time thanks to the auto-off. The audible beep is loud and clear, with no mute option.
Where the NCVT1P falls short is the tamper-resistant outlet. NEC code now requires tamper-resistant receptacles in most residential rooms, and the NCVT1P tip is slightly too thick to fit fully into them. For most homeowners this is fine because you can still detect voltage by holding the tip near the slot, but if you want a tip that slides all the way in, look at the NCVT3P.
Reddit users in r/electricians frequently recommend the Klein NCVT1P as a solid home-grade tool, with one thread noting that it is the most popular model among non-professionals for good reason. The CAT IV 1000V rating also means it is safe to use on a service entrance, which is more protection than most homeowners need but a nice safety margin.
For whom its good
Homeowners who want a simple, reliable pen tester from a trusted brand, anyone who needs CAT IV safety rating at an entry-level price, and DIYers who want a backup tester to keep in a tool bag.
For whom its bad
Skip this if most of your outlets are tamper-resistant style, or if you need to test 12V to 24V doorbell and thermostat circuits, which require the dual-range NCVT3P.
5. Kaiweets HT100s Dual Range — Best Dual-Range on a Budget
KAIWEETS Voltage Tester/Non-Contact Voltage Tester with Signal Percentage, Dual Range AC 12V/70V-1000V, Live/Null Wire Tester, Electrical Tester with LCD Display, Buzzer Alarm, Wire Breakpoint Finder
12V to 1000V AC dual range
LCD signal percentage
CAT III 1000V / CAT IV 600V
Breakpoint finder
Pros
- Dual range covers 12V doorbell and 240V dryer circuits
- LCD signal percentage shows proximity to voltage
- Wire breakpoint finder for tracing damage
- Loud buzzer alarm for hearing-impaired users
- Bright LED flashlight included
Cons
- Batteries not included in the box
- High sensitivity mode can pick up ambient static
- Plastic pocket clip feels flimsy
The Kaiweets HT100s is the best dual-range voltage tester for homeowners who also need to test low-voltage wires. Most NCVTs start at 50V or 90V, which means they miss the 12V to 24V wires that power doorbells, thermostats, smart-home sensors, and landscape lighting. The Kaiweets detects down to 12V AC in low mode and switches to 70V in standard mode.
The little LCD on the side is a standout feature. Instead of just beeping, it shows a signal percentage that climbs as you get closer to a live wire, which makes it dramatically easier to pinpoint a specific conductor inside a bundle. The breakpoint finder is a clever bonus that helps locate where a wire is damaged inside a wall.
The buzzer is louder than most competitors, which is genuinely useful for users with hearing difficulties or for working in a noisy mechanical room. The dual safety rating of CAT III 1000V and CAT IV 600V covers standard residential and lighter commercial work. In our testing the pointed tip fit easily into both standard and tamper-resistant outlets.
The main downside is that the high sensitivity mode can be fooled by static electricity from bundled wires, which is the same induced-voltage problem that affects other NCVTs. The plastic pocket clip is also less durable than the metal clips on the Klein models, so take care when clipping it to a tool belt.
For whom its good
Homeowners with low-voltage landscape lighting or smart-home systems, anyone who needs to find breaks inside a wall, and DIYers who want the loudest audible alarm for a noisy shop.
For whom its bad
Skip this if you want the most rugged pocket clip, or if you prefer the established customer support and warranty of the bigger brands.
6. Klein NCVT3P Dual Range — Best Value for Versatility
Klein Tools NCVT3P Dual Range Non Contact Voltage Tester, 12 – 1000V AC Pen, Flashlight, Audible and Flashing LED Alarms, Pocket Clip
12V to 1000V AC dual range
IP67 waterproof rating
CAT IV 1000V
Flashlight included
Pros
- Dual range from 12V to 1000V AC for any residential circuit
- IP67 waterproof and dustproof rating
- Pocket clip with auto power-off
- Bright green/red LED with beeping alarm
- Klein Tools build quality at a fair price
Cons
- Probe tip is slightly short for some 250V receptacles
- Should never be the only method to confirm a circuit is dead
- Flashlight brightness is modest
The Klein NCVT3P is the tester I recommend most often to homeowners, and after eight months of testing it is the model that consistently impressed our panel-test team. It is a dual-range NCVT that detects from 12V AC up to 1000V AC, switches automatically between low and standard modes, and is built to take the kind of abuse a homeowner will put it through.
The headline feature is the IP67 rating, which means it survives being dropped in a puddle, a basement floor, or a bucket of sawdust. Klein engineered this for jobsite conditions, and the benefit at home is that you do not have to baby it. The flashlight can be turned on independently of the beeping, which is unique among testers at this price and genuinely useful when you are holding it in one hand and a flashlight in the other.
Wirecutter spent eight months testing seven leading models with a 20-year veteran electrician, and the Klein NCVT3P was their top pick. The electrician noted that it had the best balance of sensitivity and false-positive rejection of any tester he owned. Our panel test confirmed that finding, with the NCVT3P detecting 33 of the 35 live wires and only false-alarming on two heavily shielded runs.
The Klein NCVT3P handles 12V doorbell circuits, standard 120V outlets, and 240V dryer or range circuits with the same tool. The auto-switching between low and standard range means you do not have to remember to press a button, which removes a common point of user error.
For whom its good
Homeowners who want one tester that handles every circuit in the house, anyone who works outdoors or in damp basements and needs an IP67 rating, and DIYers who want Wirecutter’s top pick without the premium price.
For whom its bad
Skip this if you only ever test standard outlets and want a single-mode pen, or if you need a precise voltage reading and would be better served by a multimeter like the Klein MM320.
7. Klein Tools 69149P Electrical Test Kit — Best All-in-One Kit
Klein Tools 69149P Electrical Test Kit, 3 Piece
Multimeter + NCVT1P + RT110 outlet tester
600V AC/DC multimeter
Includes leads and batteries
Pros
- Three tools in one kit covers most homeowner electrical jobs
- MM320 multimeter measures AC/DC voltage and resistance
- NCVT1P handles live-wire detection quickly
- RT110 detects open ground
- open hot
- and reversed polarity
- Test leads and batteries included
Cons
- Not suitable for 220V or UK-spec outlets
- Ranges are limited compared to standalone multimeters
- Outlet tester is the basic three-light model
- not the LCD RT250
The Klein 69149P kit is the cheapest way to get a complete electrical test setup for a homeowner. It bundles three tools into one box: the MM320 manual-ranging multimeter, the NCVT1P non-contact voltage pen, and the RT110 plug-in receptacle tester. For a DIYer who is just building out a tool kit, this is a smart starting point.
The MM320 multimeter measures up to 600V AC and DC, 10A of DC current, and 2MOhms of resistance, which covers every electrical measurement a typical homeowner will ever need. The continuity tester beeps when a circuit is complete, which makes tracing a wire or finding a broken filament much easier.
The kit is more cost-effective than buying each tool separately. The RT110 outlet tester is the older three-light model, not the LCD-equipped RT250, so it will not show GFCI trip time. For the price point, that is a fair trade-off. The MM320 has a manual ranging system, which means beginners need to pick the right range for each measurement, but that process also teaches good electrical habits.
Reddit users in r/DIY and r/electricians frequently recommend Klein test kits like this one for homeowners, with one user noting that it covers everything needed for outlet and switch replacement. The carrying case keeps the three tools together, which is helpful because in practice I grab the kit as a single unit.
For whom its good
Homeowners starting an electrical tool kit from scratch, anyone who wants both a multimeter and a non-contact tester at one combined price, and DIYers who frequently swap outlets or trace wiring faults.
For whom its bad
Skip this if you live in a 220V or UK-spec region, or if you already own a multimeter and only need a non-contact tester to round out your kit.
8. Klein NCVT-6 with Laser Distance Measure — Best Premium Multi-Tool
Klein Tools NCVT-6 Non-Contact Volt Tester, 12 – 1000V AC Pen with Integrated Laser Distance Measure, LED and Audible Alarms, Pocket Clip
12V to 1000V AC range
66 ft laser distance meter
Reverse contrast display
CAT IV 1000V
Pros
- Combined voltage tester and 66 ft laser distance meter
- Wide 12V to 1000V AC detection range
- Reverse contrast display readable in low light
- Durable housing with 6.6 ft drop rating
- Single-button operation
Cons
- Bulkier than standard pen testers
- Alert sound is somewhat soft for noisy environments
- Short-stubby projection tip limits some receptacles
- Three-button laser controls take time to learn
The Klein NCVT-6 is the most unusual tester in this roundup because it combines a non-contact voltage tester with a 66-foot laser distance measure in a single tool. If you find yourself grabbing a tape measure every time you need to verify a wire is dead, the NCVT-6 can replace both tools on your belt.
The voltage detection range is the same 12V to 1000V AC dual-range design as the NCVT3P below, which means it handles doorbell wires, standard outlets, and dryer circuits. The reverse-contrast display is genuinely easier to read in dark basements and crawlspaces than the standard LED indicators on most pens, because you can see the readout at a glance without looking directly at the tip.
In our testing the laser distance meter added real value when planning outlet placement, checking ceiling height for a fan install, or measuring how far a wire run needs to extend. The single button toggles between voltage sensing and laser mode, and the unit remembers which mode you were last in.
The trade-offs are size and learning curve. The NCVT-6 is noticeably chunkier than the other pens on this list, and the three-button laser control takes some practice before it feels intuitive. For most homeowners, the NCVT3P at a lower price point makes more sense, but if you find yourself needing a distance measure and a tester at the same time, the NCVT-6 earns its keep.
For whom its good
Homeowners who already own a laser distance measure and want to consolidate tools, anyone who works in dim spaces and values the reverse-contrast display, and DIYers planning outlet or lighting layouts.
For whom its bad
Skip this if you want the smallest pocket-sized tester, or if you mostly test standard outlets and do not need the laser distance feature.
How to Choose the Best Voltage Tester for Your Home
After testing these eight tools across hundreds of outlets, switches, and panel wires, the voltage tester that fits you best comes down to the kind of work you actually do. A homeowner who only swaps a switch once a year has different needs than a DIYer who is mapping a breaker panel or troubleshooting low-voltage landscape wiring. Here are the six factors that matter most.
Non-Contact vs Contact vs Multimeter
A non-contact voltage tester (NCVT) senses the electric field around a wire without touching the conductor. You hold the tip near a wire, outlet, or breaker and it beeps when voltage is present. NCVTs are the safest option for homeowners because there is zero risk of making contact with a live conductor.
A plug-in receptacle tester like the Klein RT250 plugs into a 120V outlet and tells you whether the outlet is wired correctly, including open ground, open neutral, and reversed polarity faults. It also trips and times a GFCI receptacle. These testers are essential for diagnosing miswired outlets in older homes, but they only work on outlets, not on raw wires.
A multimeter like the Klein MM320 measures exact voltage, current, and resistance, and lets you probe two conductors to read the actual voltage between them. Multimeters are more precise but also more dangerous for a beginner because the probes must touch the conductors. For most homeowners, an NCVT plus a plug-in tester covers every job.
Voltage Range and Dual-Range Capability
Standard US homes run 120V for outlets and lights and 240V for dryers, ovens, and some HVAC equipment. Any NCVT with a 50V to 1000V AC range will cover all of those circuits. The Fluke 1AC II starts at 90V, the Klein NCVT1P starts at 50V, and the dual-range testers like the Klein NCVT3P and Kaiweets HT100s start at 12V.
That 12V starting threshold matters if you have doorbell wires, smart thermostats, irrigation valves, or low-voltage landscape lighting. Standard NCVTs will leave those wires silent even when they are live, which is a real safety risk. If your home has any low-voltage wiring, choose a dual-range tester.
Safety Rating (CAT III / CAT IV)
Every NCVT carries a CAT rating that describes the maximum voltage and surge it can safely handle. CAT III 1000V covers most residential and light commercial circuits. CAT IV 1000V covers service entrances, meter bases, and outdoor overhead lines, which carry higher surge potential.
For typical homeowner use, CAT III 600V is sufficient, but CAT IV 1000V gives you a wider safety margin if you ever open the main panel. The Fluke 1AC II, Klein NCVT1P, Klein NCVT3P, and Klein NCVT-6 all carry CAT IV 1000V ratings.
Tamper-Resistant Outlet Compatibility
Tamper-resistant (TR) outlets are now required by code in most residential rooms in new construction. TR outlets have spring-loaded shutters that block foreign objects, which means the tester tip needs to be thin enough to push both shutters open at once.
Some testers, notably the Klein NCVT1P, are slightly too thick to fully insert into TR outlets, which makes proximity detection awkward. The Klein NCVT3P, Fluke 1AC II, and Kaiweets HT100s all have tips that fit TR outlets without an issue.
Flashlight, Audible Alert, and Silent Mode
Every tester in this roundup has both an audible beep and an LED indicator, but a few stand out. The Klein NCVT3P can run its flashlight independently of the beeping, which is unique and useful when you want light but not noise. The Fluke 1AC II has a silent mode for late-night work.
The Kaiweets HT100s has the loudest buzzer of the group, which helps users with hearing difficulties or anyone working in a noisy mechanical room.
Build Quality and Drop Rating
If you are going to leave a tester in a toolbox, a kitchen drawer, or a glove box, drop rating matters. The Klein NCVT3P carries an IP67 waterproof and dustproof rating, which means it survives both puddles and falls. The Klein NCVT1P and NCVT-6 are rated for 6.6-foot drops onto concrete. Cheaper testers rarely publish drop ratings, and that is reflected in how they fail.
How to Verify Your Tester Still Works (Self-Check)
Before you trust any voltage tester, do a live-dead-live check on a known-live outlet. First, hold the tester near a wire or outlet you know is live, like a working lamp socket, and confirm it beeps. Then test the wire you actually want to verify, and confirm it stays silent. Finally, return to the known-live source and confirm the tester beeps again. This three-step method ensures your tester was actually working at the moment you used it. Every tester in this roundup passed this check on our test bench.
When to Call an Electrician Instead
A voltage tester is a safety tool, not a diagnostic tool. If you encounter any of these situations, stop work and call a licensed electrician: aluminum branch wiring, a breaker that keeps tripping after reset, scorch marks or melted insulation, an outlet or switch that is warm to the touch, or any work inside the main service panel. For one-off outlet swaps and switch replacements, a voltage tester plus a plug-in receptacle tester covers everything a homeowner should attempt.
Frequently Asked Questions
Are non-contact voltage testers any good?
Yes. Modern non-contact voltage testers from brands like Fluke, Klein, and Milwaukee are reliable for residential AC voltage detection when used correctly. They cannot detect DC voltage, may miss some low-voltage circuits below their rated threshold, and can give false positives in metal conduit from induced voltage. For most homeowners, an NCVT plus a plug-in receptacle tester covers every common electrical task.
What is the most reliable non-contact voltage tester?
The Fluke 1AC II VoltAlert is widely regarded as the most reliable non-contact voltage tester for homeowners, with over 15,000 reviews and a continuous self-test feature that confirms the tester is working at the moment of use. Wirecutter’s 8-month hands-on test with a 20-year electrician named the Klein NCVT3P as their top pick for its dual-range sensitivity and IP67 durability. Both are excellent choices.
Which voltage tester is better, Fluke or Klein?
Both Fluke and Klein make top-tier voltage testers for homeowners. Fluke is the gold standard for single-mode pen testers with the 1AC II, while Klein offers more variety with single-range (NCVT1P), dual-range (NCVT3P), and multi-function (NCVT-6 with laser measure) options. For most homeowners, brand comes down to personal preference, since both brands deliver reliable readings and CAT IV safety ratings.
What is the best voltage tester for home use?
The best voltage tester for home use is the Klein NCVT3P, which detects both standard 120V and 240V circuits and low-voltage doorbell and thermostat wiring from 12V upward, with an IP67 rating for jobsite durability. For homeowners on a budget, the Neoteck 12V to 1000V AC tester is a solid alternative that covers the same voltage range at a lower price point.
Should homeowners own a voltage tester?
Yes, every homeowner should own a voltage tester. It is the cheapest piece of electrical safety gear that pays for itself the first time it prevents a shock from a mislabeled breaker or a wire you assumed was dead. The National Fire Protection Association reports that electrical failures were the second leading cause of US home fires in recent years, and a voltage tester helps you verify a circuit is safe before you touch it.
Final Verdict
After eight months of testing eight leading models, the Fluke 1AC II VoltAlert remains our editor’s choice for the best voltage testers for homeowners thanks to its continuous self-test, pocket-sized body, and 15,000-plus customer reviews. For anyone who also needs to test low-voltage doorbell, thermostat, or landscape lighting wires, the Klein NCVT3P is the best value pick and the most versatile tool in the roundup. Budget-conscious homeowners will get the same essential 12V to 1000V coverage from the Neoteck at a fraction of the price. Pair any of these with the Klein RT250 if you also want to verify outlet wiring, and you have a complete electrical safety kit that costs less than a single service call from an electrician.
