yes I have tried them, IMO it is just another of those wonderful snake oil products.
also keep in mind these run thru the cig lighter, and since ours are not active when the car is not running, (they are switched off) they will do nothing for you unless you rewire that connection to be always hot.

There are many car dealerships that use them. They don't use them to charge the battery, just to keep it topped off. I believe most plug in trickle chargers are only 1.5A so a solar panel should be able to supply that. I don't see how it can drain your battery as it doesn't draw power, only supply it.
