I'm the OP on that thread. It's been installed for barely over one day now. So far it's been fine, but with a major caveat: When the unit arrived, it was missing its back plate. I contacted eMotorWerks via both their Web form and phone, and they sent out the missing back plate and screws via 2nd-day delivery. I initially thought the screws were missing, but I later found them buried in the packing material -- too late, as I took the whole unit to the hardware store and spent half an hour finding screws that fit. Anyhow, that's a pretty embarrassing quality control problem on the part of eMotorWerks. (At least, I assume it's an eMotorWerks screwup and not a Clipper Creek screwup; since these units are sold through eMotorWerks and not through Clipper Creek, my assumption is that Clipper Creek sends them to eMotorWerks, which then adds their JuiceNet board and ships them out.) This mixup makes me a bit wary of eMotorWerks, and in fact I nearly returned the box in favor of a plain-vanilla Clipper Creek or ChargePoint unit. Now that it's installed, though, I'm provisionally happy with it. We'll see how it survives the Rhode Island winter.
By my list in my previous post, I did not mean to slight any others; those were just the ones I was considering. By my research, it looks like there are a lot of options in level 2 EVSEs, and I found none that are flat-out bad, if user reviews are any indication. They differ in amperage, cord length, pricing, weatherproofing, miscellaneous features, styling, and place of manufacture. I'd recommend focusing on the first three of those first, then subsequent issues as your needs and desires dictate. That'll help narrow the field.Leviton makes a nice looking 40 amp unit too,
