[This review was collected as part of a promotion.] I tried this in three different locations in my house, just because I wasn't sure where I wanted to put it, or where it would make the most sense. Eventually, I decided that I needed to turn a one-gang receptacle location into a two-gang so that I would not lose any 120 volt receptacles. I think it was the right choice, and it looks the best. I have it in my kitchen now, above the section of countertop on the side of the kitchen that collects everyone's phones, tablets and laptop. It was the "charge center" of the kitchen before; with this 4-port USB charger, it now works much more efficiently and looks a LOT better. It fit the back box properly, the wall plate fit around it properly, and it came with wires pre-installed so I was able to wire it direct to the GFCI outlet next to it (see the pics). Other than the work it took me to change the one-gang box to a two-gang, it was easy to install. I like it, and my wife likes the way it looks - especially compared to the mess of large USB to 120-volt adapters we had to try and rearrange before.
