My Juice Box has been totally reliable. It is over one year old at this point. It charges a Miev and a Bolt, with not even a sign of incompatibility.
I got it because of reviews like my own. But, I did have a real professional double check and install a 14-50 on the wall. Thus, I plug in the Juice Box. It is simple to ever reset, since it is plugged in. *Only did that during an initial setup.
I've been here. I've been there. And I've been in-between.
