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 Daryle Grove

This is the second Dingsun auto switcher I've purchased. As of this review, both have given me zero issues over their life time. Every other brand I've tried has ended up in the trash due to intermittent losses of input to the display. The issues seemed to be related to the various other brands not having been designed with a means to handle variations in power quality. Issues would show up usually within a month or two and steadily get worse. Dingsun has my vote.
