  1. JoeGlider

    Excellent meter, very reliable and accurately.

    I love this meter since the 1st day I bought it. It is very handy, have an excellent clear display and it is very accuarate, which fot the tipe of work I do it is very important. It is not too expensive and everybody should have one of this handy. I love all the features it offers including an ergonomic touch which make this meter the best meter of its kind.

    ✔ Yes, I recommend this product.

    bigger is better!

    as an industrial and commercial electrician for the last 25 + years, I have literally profited from the use of Amp probe meters. this particular model has the wider jaw so you can easily test wires greater than 500 kcm. Reliability, support and ease of use are some of the key features you will enjoy. It never hurts to have the edge over ethe guy standing next to you.

    ✔ Yes, I recommend this product.

    Great Functionallity

    A great reliable meter able to test several different application

    ✔ Yes, I recommend this product.

  4. Joe22

    Item works ok

    Problem I find with this clamp on meter is the slide switch
    is hard to adjust what scale you want to select. Its very easy
    to move, bu easily slides over the position you actually want. It
    would be better if it were a rotary switch.

    ✘ No, I do not recommend this product

  5. Bryan44

    This product is my “go to” meter for 99% of my needs

    I have owned this clamp meter for several years now and am always impressed with the ease of use and accuracy of the readings.
    I have used many other multimeters and clamp meters before, this one offers great value at a great price.

    ✔ Yes, I recommend this product.
