    Don't buy! Doesn't work if your battery is dead:-(

    I bought one of these because my car was having trouble starting - it was fine when I jumped it from another car, and would be fine for days afterwards, but this was utterly useless when I really needed it - I wound up having to call AAA and wait for an hour anyway. I think it might possibly work if your car's battery was mostly okay and only needed a little help, but as it turns out, my battery was at less than 50% capacity, and this didn't turn the starter turn over once! >:-( Really not worth they money - buy something better that actually can hold a charge.

    No, I would not recommend this to a friend
