I base it upon the fact that I have seen many of them fail
rather than work. Generally it has resulted in the destruction
of either the starter or house battery or both.

I don't like them. They don;t provide an optimal

Eliminator from
AmplePower or an EchoCharge from Balmar. They provide a
better charge for the starting battery.

What do you base this upon?
