    Worth the money by far

    We had just purchased a Amprobe AMB-25. As soon as we went to use it the engineers and electricians both stated it’s easy to learn how to use and seems very accurate.
    All six of them said they would recommend this product and are glad we now have one to use.

    ✔ Yes, I recommend this product.
