I am going to have to drop my original rating to 1 star due to product just doesn't work as advertised

Other than the fact I was afraid it was going to burn my car down, it worked as advertised

Worked as advertised, had no trouble hooking it up but with the included instructions (or lack thereof) some may need assistance in hookup.

Works as advertised and simple to set up.

Made everything work as advertised.

All in all it works as advertised and I would recommend this product..

When I flipped the switch, it was almost as good as when it was sitting on my workbench.
