Works well but poor select button
I installed this device without difficulty, and it does the job well. It recognises if a new connected screen is on and switches automatically: this is good. There is no visible loss of quality in the output video. The only drawback I've encountered since the first day I received it is that the "Select" button is rotten on the model I received! When pressing it, no reaction: the button seems stuck. When pressing harder (reasonably, not like a brute), the button progressively sinks inside the device after each solicitation! It seems that the metal part that holds it twists when the button is pressed. Impossible to bring it back to its initial position. Fortunately there is a remote control, which is now my only way to switch on and off the screens connected to this device. I'm a bit phlegmatic about sending back a device at this price, but the manufacturer should reconsider this.
