Review on 🔁 Hassle-free 4K HDMI Matrix Switch 4 X 2 by Orei - UltraHD 18G Switcher with Arc, 4K @ 60Hz & 1080P Support, IR Remote, and Full Matrix Selection (UHD-402) by Sabryna Wickings

Update - 1 year and 1 month later. This device has failed. It started with the loss of sound, the frequency of which increased, then the video disappeared, and finally disappeared completely until reset. If it was a $20 device, fine, but it's not, and 1 year of semi-stable use to failure means . buy something else. ------------ So far, so good. I bought this to connect multiple HDMI sources to my projector and get sound out of the Sonos Beam via the optical out. I just encountered a potential issue with the output from certain devices in certain situations - can't transfer image. Also, it was good for the purpose I've bought it for so far.
