I bought this projector from best buy four months ago for $229.99 and I don't use it. It's a great device though. It can be used without being plugged into a power outlet and the picture is really good. Also it doubles as a really good Bluetooth speaker. I just never use it cause I have my big screen TV and I don't have any blank walls to project onto. It is great for any kind of video and it can be used remotely, like inside a tent or outside. It requires an hdmi cable.
