It keeps jumping until you give up

We tried this for the first time on our kid's car. We didn't understand that their car battery was toast, so tried the Battery Jumper a number of times. Car would start. We would unhook charger. Car would stop. Repeat. Repeat. The Battery Jumper had a good sense of humor and kept firing up the car. We tried all variations, but someone sitting in the car giving it gas worked best — still failed as soon as the assistant stopped coaxing the car to run. It needed the alternator to be running. Best move was to call AAA for a new battery delivery! But the Battery Jumper performed above and beyond the call of duty until we finally gave up. I recommend it!

I haven't had a chance to use it but it appears to be a very good unit. I like the light that's on it to be able to see what I'm not doing right. The battery level LEDs would really help and it's rechargeable via USB.
