Wall plugs like this have been around forever but this one is so clean and simple, that you really can't beat it. Especially for the price. It doesn't block both outlets so you are net adding 2 plugs, plus 2 usb ports. So many devices nowadays go through USB and you usually end up having a million of those little USB bricks plugged into your outlets or power strips. This allows you to get ride of those and go straight USB into this device. For the price of these things, I may end up sticking them on a bunch of outlets around my house. Recommended!
