Review on Convenient Wall Mount Power Strip: 4 AC Outlets, 2 USB Ports, 45° Curved Plug, 6.5FT Cord - Gray by Joseph Flamm

One of the main reasons I chose this one is that the plug fits snugly against the wall and doesn't protrude. It's really useful for furniture. The exit end of the box is plastic, which I wasn't sure about from the photo. It almost looks like painted metal in the photos, but it's not plastic. It's fine for my application, but if you're using it in an area with a lot of potential impact, you might need the strength of the metal. It's a good solid plastic and like I said it fits what I need. The inclusion of two small USB power connections is also practical.
