Awesome tool

Thought my radiator fan was dead, turns out after buying a second fan, and testing it, thinking it was dead too, did I think to test the brand new power prob. That was the problem. Get a different brand if you can. Likely just a fluke but they said they tested it before shipping, so.... Yea.

Does what it supposed to excellent product fast delivery!!!

I have forty years fixing all kinds of mechanical stuff. This tool barely works. Picks up signal barely. Tool is not functional. Buy something else.

handy thing to have

This unit works great for the function of witch it was designed. Dont spent a lot of money on the same thing from other brands this one works just as good.
