  14. Gregnb3

    Nice go to meter

    I use this meter when I have small stuff to check. As a mechanic it gets beat around and tossed in the tool box and don’t miss a beat. I wish their was a better automotive geared meter by amprobe. I have a 400 Mac meter but it only comes out when testing has to be sent to my laptop via the usb. Nice little meter and worth the cash!

    ✔ Yes, I recommend this product.

    Love this meter it is my go to even over my fluke or craftsman

    I love this meter never had a single problem out of it. Easy to use and read i mainly do automotive testing and mainly look for power at a certain wire so i havent really gotten in to may of its features (i could uses a test light for most of my wor but like a mter over that method) i have a fluke and craftsman meter aswel but 9 chance out of 10 i find this meter in my hand over both of them. Over all great product only time will tell it has held up great so far! Overall extremely pleased with this tool (meter)

    ✔ Yes, I recommend this product.

  18. karl98

    Great meter, very solid

    I’m not an electrician so I haven’t really put this thing through its paces but so far it has been super useful at checking battery voltages or if a wire is live. The probes don’t feel cheap and the meter itself feels substantial.

    ✔ Yes, I recommend this product.

    Definitely DIY

    Great for the occasional electrical repair or troubleshoot. Probably wouldn’t use it every day for a living. Seems well built, easy to read, although the numbers seem to “hunt” for a strangely long time sometimes. Not a big deal.
