I got my charger installed this week, less than two weeks after enrolling. The tech that came out said it was the fourth install he's done so far. I didn't have to change my usual scheduled charging settings in my car, but the charger itself was not set to off peak only by default. Having a longer cable than my semi-permanebt Gen1 mobile charger install is nice. Pushing the button on the charger does unlock the charge port, so I can pull the adapter out with the 1772 wand as a single unit. They also sent a charger that matched what I had for a circuit and confirmed it again before install, so I'm getting the full 40a possible for my install.
So far, I'm happy. By my calculations, I'll be saving $60-80 a month after the $31 a month program charge.
