Bought this as a switch for my TV as only 1 HDMI port works. Product works as described. Does not require power which was surprising, gets its power via the HDMI signal. Signals auto switch when turning something on however is does not auto switch back after a device is turned off which is a downside. All in all I recommend, good price, good quality. no noticeable lag when displaying either PC or PS4 Pro
Just bought a Nintendo Switch and didn't have enough hdmi ports to fit everything, this device came in super handy to plug everything in, and it doesn't clutter the TV room because of the size, easy to set up and easy to user, highly recommended.
Delivery was prompt. Most of the time it works well, but a couple of times a week, the auto-switching fails, so I'm left with a screen full of static and need to then reboot the the attached IPTV set-top box, because the switching is not being triggered. It's cheap, so I'm not overly fussed about it, but would prefer that something paid for works every time.
Product works as advertised. Switches automatically between sources based on most recent power-on. Remote receiver is IR, so requires direct line of sight. Does not include a HDMI cable to go from device to screen, so you will need a spare.
