Saves aggravation

I installed one of these on a friend's rarely driven Cadillac several years ago. Finally spent the money and put one on my occasionally driven Jaguar. Works great and much better than having to start the car every week to keep battery charged, or disconnecting and reconnecting battery. Easy install, delivered on time. Pricey but worth it for lazy guy like me.
