Review on ELECROW 7" Portable Raspberry Touchscreen - CapACitIve, 1024X600 Resolution by Jason Lambert

I received this as a wearable screen to use with RetroPie. It's small enough to carry around, big enough for high visibility, and the fact that it comes with speakers is a bonus too. It even has physical controls on the side for volume and screen brightness, which I haven't seen on most other screens I've tested. It was pretty easy to set up and comes with a small screwdriver, you don't even need any tools. I chose not to mount my Pi on the back of the screen, but it does have a mount point if that's what you want.
