The function is a cool design, power is not too bad, how quickly it charges depends, I would like to have it cheaper because so many components move that it seems like it can break anytime. The fit on the outlets is tough because how big and awkward it is. The return tension with the cable already seems like it's breaking and the plug to the outlet is scary. You can move 1 prong at a time... Seems like it will fall off soon. Only used it a month and it's acting up. It's cool and does its job. Might be broken soon.
