Matco mini jump box

has anyone used one of the new mini jump boxes they have out. there are several places popping up with them. the one from matco is the one i was being told about and thinking i may get one. they are supposed to be pretty good. here is a link if you dont know what im talking about

a couple friends who work at a dodge dealer swear by them. they said they work great on small stuff. they have only used it on a diesel one time, said the truck would barely turn the dash lights on. said it jumped it right off.

thank you, i done a search by title and didnt see any.
