This works great to find trailer wires by putting power to unknown wires.

I like the product works really good for check Fuse or electric shorts on car and truck

I purchased this as a replacement for one that I had for a while it worked great already paid for itself.

Quick testing and troubleshooting.

Great tool for the money, works as it should.

Does a great job for the money

Tis works very well .

Auto repair

hasta ahora a funcionado como debe, me ha permitido realizar comprobaciones a vehículos y así poder diagnosticar falta de voltajes en los mismos

Works exactly like it’s intended. I like that you can throw power to a device to test
