Review on 🔌 Fosmon 3-Port HDMI Switch with HDR, HDMI 2.0, HDCP 2.2, 4K@60HZ 1080p: Wall Mountable Switcher Splitter + 3-Pack Durable 6FT HDMI Cables by James Dominick

The automatic switch only works if you can turn the device on or off. Since the Roku boxes are always on, at least for me, this doesn't switch to the Roku input unless you go to the jack behind or near the TV and toggle it manually. It's inconvenient to do. Also, the switch doesn't appear to be powered by the devices attached to it, despite the specs saying so. I had to use the included micro cable for power, but I had to buy a USB adapter separately to use it. Before you buy, make sure your configuration integrates seamlessly with it. Buyer Warning!
