    It easy to use with and read

    I like the automatic selecting and its ease of use. It’s also easy to hold with it’s slim line. It is the best voltage tester I have ever used and would recommend it to anyone.

    ✔ Yes, I recommend this product.

  2. blake124

    these amprobe product are the best for home owners

    i used this tool around the house and it works great i dont own one i borrowed it from my father and he has quite a few of your tools and he swears by them i use them all the time i would like to own my own set

    ✔ Yes, I recommend this product.

  3. Fran


    Awesome-perfect for the back pocket-can take a beating-just like the old school “wiggy” but better

    ✔ Yes, I recommend this product.

  4. Greg1

    highly recommended

    works just like the wiggy, but easier to use and see. does not lie to you like some of the cheaper digitals meters.

    ✔ Yes, I recommend this product.




    ✔ Yes, I recommend this product.

  6. Txwireman86

    This product needs work

    This product will not fit into a standard 15A-125V receptacle without removing the leads from the holders. They are spaced too far apart.

    ✘ No, I do not recommend this product

  7. joelj

    Super Durable

    I love the reliability of this thing. I am hard on my tools and testers and this one has never failed me.

    ✔ Yes, I recommend this product.

  8. SMK2012

    Good value but needs improvement

    Aside from needing to remove one probe to check duplex receptacles, it would be nice if with one probe the unit would detect ac voltage with audibility as my Greenlee 6706 tester does. This would aid in speedy fault finding of open neutral circuits. Build quality is excellent. Overall a nice compact package.

    ✔ Yes, I recommend this product.

  9. m1932

    small and easy to carry.

    This tester is small but very vesital. Will do all regular day to day needs and can be carried in your pouch. The name alone is all you need to know it will last.

    ✔ Yes, I recommend this product.

  10. 480sparky

    Good tester

    I’ve owned quite a few testers in my career and I seem to grab the amorous more than any of the rest. It’s been a good tester.

    ✔ Yes, I recommend this product.

    i have used this tester here about 60 times in the last few weeks. i had an electrical problem in my home . i had to brorrow the testerfrom my uncle . he showed and told me how to use it. i will recommend this tester to all of my friends if i am asked for a tester to use on any electrical problems that i am asked about

    ✔ Yes, I recommend this product.

  12. bayner

    This is a great tool and has a lot of really good features

    This tool has a lot of great features an isvery useful fot testing voltage and continuity of electrical circuits.

    ✔ Yes, I recommend this product.

  13. texan50

    Great, single hand tester

    When you don’t have an extra hand to hold a test lead, this tester is perfect. I use this Amprobe tester everyday working on HVAC equipment. It is definitely my “RIGHT-HAND” helper when it comes to testing the high voltages of chillers and boilers.

    ✔ Yes, I recommend this product.

  14. msk942

    This is an excellent tool for any electrician, whether a beginner or a pro.

    The one thing that I think is the best feature on the tester is the ability to place both leads in the holder and the spacing. It makes it easier when performing the job, especially in tight places and only hae one hand available to move around. The size is perfect and not bulky as some can be.

    ✔ Yes, I recommend this product.

  15. 123Dick

    Compact & Easy to use

    The Amprobe VPC-31 Electrical Tester is a slick compact instrument that is easy to use. Its size and LCD readout make it usable even for the novic who needs to check a circuit. I would highly recommend this product as a valuable addition to your tool bag.

    ✔ Yes, I recommend this product.

  16. Kevin

    Good for testing old woring jobs

    My house was built in 1930 and the wiring was added later but is very old. This is a great tool to use for testing old worn out wiring that needs to be replaced.

    ✔ Yes, I recommend this product.

  21. IEJoe

    Great protection for the price. Well done.

    I say protection because we rely on testing equipment to keep us informed and safe when troubleshooting. Well built , love the auto ranging, simple continuity checks, bi color leds go red or amber dependent on voltage present. Leads are impressive and have some tip options that come with the meter. I was looking for a meter for my small VETO TP3 diagnostic bag and it fits nicely in the bag as well as provide basic functions needed to start troubleshooting. I am considering this as a gift this Holiday as not everyone is a gearhead or electrical tech, “great Do It Yourself Tool” as it does everything for you. I added a cord minder velcro strap to the removable lead so when I wrap the cord around the handle portion it holds it securely in place and is not sticking up above the bag. I would have printed the Non-Contact Voltage Range to the right side of the LCD so when you leaned the left non-contact side it would remind help you remember the – dash code for the voltage. Appreciate the the quality in the meter believe you have set a standard.

    ✔ Yes, I recommend this product.

  22. TomM

    It Works!

    I purchased one of these and my sons were so impressed that additional ones made great Christmas presents! This tester makes safety paramount!

    ✔ Yes, I recommend this product.

  23. Sparkie

    Compact and full featured

    Neat compact tester that fits in you pocket or tool belt with ease
    Multi-colored LED’s lets you know the voltage your working with and the non contact voltage detection feature eliminates a tool in your tool belt.

    ✔ Yes, I recommend this product.

  24. ReddyElectric

    never leave without it!

    Works perfectly. I use it daily. Durable, and easy to read…

    ✔ Yes, I recommend this product.
