    I use it all the time

    This product I carry with me all the time and it’s like not having a pen when I don’t carry it?
    My reasons for using this is 1. cost (I have lost 2) 2. ease of use 3. small in size comes in so handy without needing a wiggy or VOR meter.
    My main concern is to double check and make sure all wires are dead before touching ANY wires?
    If your not sure GET A METER!

    Thanks Bruce

    A Must Have

    This is as improtant in your pocket as your keys. I use this everyday to make sure the power is off when i am working. This tool will give you peace of mind that the breaker you shut off was the right one or that the other guy shut off the right breaker. Save lives and dont burn up parts buy a couple and keep around.

    ✔ Yes, I recommend this product.

    Life Saver

    I do not own a volt detector but have been able to use one before. I was describing to a maintenance man at my work one time about needing to work on my ceiling fan. He offered his volt detector to use for the day. I am glad I did. I flipped the breaker I knew operated the light but apparently there was a separate breaker for the wire to the fan. If I had not been able to use his Amprobe volt detector, there is no telling what could have happened to me.

    ✔ Yes, I recommend this product.

    Excellent Pocket device

    This volt tick is a great small device to avoid finding a live wire where you don’t expect it. Not having to run and get the large tester or going to the circuit breaker panel to check every time is a god send. I highly recommend this procduct.

    Every DIY’er should have this for those electrical jobs

    Compact, easy to use and carry, even in tight places. Not exagerating when I say could be a life saver.

    ✔ Yes, I recommend this product.

    This is a very robust non-contact tester

    I use this tool instead of a fluke the cost is much better and you don’t get the annoying beep or constant flashing you get from other non- contact testers. This is a very good product and robust I have dropped mine from a knuckle boom and still it works. Great job guys.

    ✔ Yes, I recommend this product.

    One of the handiest tools I have!

    We recently moved into a new house that had a bit of unfinished work. So when it came to tracking down the 220 lines in my garage, this is the tool I went for! I was told there was a 220 line but not sure where to look. This Volt Detector saved me from having to call a pro & pay them the min charge to track it down.
    Small, compact, fits nicely in my tiny tool box! I now use it every time I need to check whether a line is hot, 2 on my front porch were just hanging out of the wall, I found out that one of them was hot BEFORE my dog licked it!

    ✔ Yes, I recommend this product.

  9. Diligance

    Here is where it fails

    While the tester works properly there is an issue with the rating.
    Amprobe lists this product on their website as having a range of 100-1000volts and also 110-1000 volts. The individual package specifies the range as 50-1000volts. Every competent electrician knows this is a big difference with totally unique operating characteristics between ranges. This tester has the characteristics of the higher range. Contacted Amprobe/John Fluke who promised a definitive answer that never came. I cannot recommend a product that has 2 different listed ranges.

    ✘ No, I do not recommend this product

    Excellent Safety Tool.

    I have owned/used the other various brands and find that the VP440 is the most reliable. I started using the VP440 in 2005, and has been the only one I carry and use since. I have had very few false indications of voltage when checking with the VP 440 NC voltage tester. It is an excellent safety tool to indicate the possibility of voltage, but a volt meter should be used to verify if voltage is present. I always carry one when at work and check it on a known live receptacle/circuit before each use. The company where I work, safety program, encourages the use of NC voltage testers to check for the possibility of voltage as a safety tool and requires testing with a volt meter to verify.
