I'd appreciate any comments on the good, bad, or ugly. Thanks!

They work. Sort of. They help a tired battery start a car.

I had a mustang convertable with about ten bulbs that came on if the
door was even slightly ajar. It would kill the battery stone dead in
less than an hour. I hooked up a ten amp charger and in the five
seconds it took to walk to the door, reach in through the window and
twist the key it had enough juice to start. It doesn't necessarily
take much as anyone who ever started an aircraft engine by pulling on
the prop would tell you.
