Review on 4-Port HDMI Switcher With IR Remote Control, Supports HDMI 1.4 And HDCP 1.4, 4K@30Hz Ultra HD 3D/1080P Compatible With Fire TV, Roku, PS3, PS4, Xbox, Apple TV, DVD (4X2 HDMI Selector) by Larry Lackings

As a HDMI switch, it functions alright. It can switch to the "active" device (i.e. if I power on my video game console, it will change to that input). The picture quality seems fine.The main drawback is that the IR sensor overlaps with the TV's remote, so when I change the volume up or down, it causes the screen to flicker and black out for a few seconds, which is quite annoying.The Picture-in-picture feature is ok, handy for if you switch between inputs often, but with the "active" input feature, I don't use this quite as much as I thought I would.
