Bought these for the outlets on the side my kitchen island so that the phone could be plugged in and left on the countertop to charge. Mounted the USB ports facing up instead of facing down to get them closer to the counter top. Worked fine for that. I was concerned about a few things, though. 1) the little copper fins on the sides that are designed to make contact with the screw terminals on the sides of the outlet are relatively fragile especially if you try to take the plate back off after installing it. I actually broke one taking it back off. So, no dry runs here...once you put it on it is very difficult to get back off. I was able to repair mine with solder. And 2) they were not too good at making contact. Since my outlet was back wired, there terminal screws were empty. I found that I had to put a tiny jumper wire between the two left screws and one between the two right screws so that those little copper fins would have something more to make contact with. That worked and gave me a solid connection. In the end it all worked out but those copper fins need to be redesigned.
