Works great and solved my problem. It will switch back and forth automatically when powering up/down other inputs.
I bought this because when switching between my laptop and my gaming computer my LG monitor required about 7 or 8 button presses which put an undue stress on the (cheap) switch. LG sent me a refurbished monitor, but I didn't want to go through all the trouble ever again. This allows me to use one input on the monitor so the only thing I have to switch is this device which is done either manually or with the supplied remote. Or, it also works automatically as mentioned. Also, seems well built. Time will tell.
A while ago it started giving me problems for no apparent reason. Sometimes the switch just won't respond to my key presses on the remote. It has been getting progressively worse. Intermittently it will work OK, but most times now it takes several key presses to work. .
It appears to be a low battery causing the problem. The device itself works fine. I deducted 1 star because of poor battery life....
