Excellent tool
A standard test “light” will only confirm you have voltage present. This one tells you what that voltage is. I was able to determine voltage drop and find that a connection was corroded. So, it paid for itself right there in my eyes.

Test light/voltmeter
Well, built, easy to use copper clamp, which is nice instead of the steel haven’t used it much but worked very well. Would definitely recommend good price only wish it was built in the USA other than that great product.
