Check parts on the car with or taking them out, love it

Got it fast and worked great. Went to use it again after having it a month and it doesnt work and Amazon wont let me return it or exchange it. Recommend not purchasing.

Great product !

This was a great investment. Once you figure out how to use it, its great. I had to watch a few YouTube videos in order to understand exactly how it was working. Once I did, it worked great.

Enabled me to diagnose car power window. Window would not go up. Was able to use short jumper wire/ground to window motor and use this tool as power probe to actuate motor to ra it se window. Awaiting new master switch to complete repair. Best $20 spent in a tool!

Very happy with product works great

bought this as a backup for when I need to use a power probe. Now its my go to meter. Its inexpensive for daily pro use. best regards vip auto nyc brooklyns chuchero world staten island car stereo

Worth the money

Works very well as a test light and also displays voltage rather than just a bulb lighting up with a standard test light. Also the ability to hook the alligator clips to the battery and be able to add 12 volt power or a ground to a given circuit or accessory is also very useful when trying to trouble shoot electrical issues.

Works well for the price. The cord is long and usefull when working on large RVs
