I don't see reviews where it destroyed the battery, just a few that say it "killed it", by which they mean the battery drained. Perhaps they didn't have it hooked up properly, or it didn't get enough sun (it only puts out 167mA max, so being behind glass, or in the winter will drastically reduce output). If you have a load of 100-200mA in the car, then it won't be able to keep up. Also it seems these aren't very well weather proofed, so it might be a good idea to seal it up better with silicone if you use it outside.

I used it this winter for a car that is not driven much and parked on the driveway most of the time. It saved the battery and car started every time.

The cheapest I see it is $17.95. Price must be store specific.

Some cheaper chargers don't have the required diodes to prevent the current from reversing and draining the battery when the panel isn't producing enough voltage. Not sure if this one has this problem, but it is possible that if it doesn't get enough sunlight that it could drain more at night than it charges during the day.

EDIT: Reading the description, it appears as though it shouldn't discharge the battery "Built-in blocking diode prevents reverse discharge in battery"
