Still pretty new, working out the bugs, I guess. Our local ones had some issues initially, but seem to be working fine now. We have one close by (10 min drive, but on the way to and from other shopping), so charge there most of the time now, instead of using a free level 2 as before, which was a 15 min walk from home. And our charges at the PC are usually only about 20 min, as it starts to slow down at 70%. Only issue is the Starbucks there, as my wife can't avoid the temptation... Have yet to ever wait for one, as not used heavily. I think most people don't know you can charge for free.
