Review on Dingsun 5 Port HDMI Selector With Remote And PIP Function - 4K@30Hz, 3D Compatible For Fire Stick, Roku, PS3/4, Xbox, Apple TV DVD - Auto/Not Auto Function - HDMI Switcher (5 In 1 Out) by Pushkraj Love

I bought this because at the time it said it supported picture in picture and I needed that function. Unfortunately, the "picture" it offers is three very tiny thumbnails that you can barely see just to indicate which input you are switching to. Useful but not what I needed. Works great as a switcher though. My brother is really enjoying it. The only complaint he has is that the remote feels like it could snap in half with little effort.
