It has made it so much easier for me to operate a desktop PC and a laptop with one monitor and keyboard/mouse/sound card shared between them. I have been using it daily for a year now and there has not been any problem!

The only downside is that the dedicated USB port it has for the keyboard was disabling some shortcuts on the keyboard, because it had them programmed for certain hot keys so you could switch computers without pressing the button. I simply plugged it into a regular USB port and everything was fine.

It works properly without any issues; if sometimes the screen doesn't turn on during the switch, just press the button and switch again.

It is very normal for something not to work sometimes because essentially during the switch, the computer essentially "turns off" and "turns on" USB & HDMI; after all, you can hear it from the speakers like a shutdown.

Overall unreliable, USB devices frequently disconnect and require unplugging and replugging for the computer to recognize them again, while recently the HDMI has started flickering and producing momentary green flashes on the screen. I'm expecting it to completely break down soon, which seems to be inevitable, so I can send it back where it came from.

He does the job he is supposed to. I had an issue with the handling of keyboards and mice and it was solved as soon as I changed their position from the one that was anticipated... Everything is okay then.
