Used together with a Digitus DA-70118 USB to PS2 adapter / USB AM to 2x mini-DIN 6F with an IBM keyboard and a USB mouse. Connected to three computers, the switch works very well. The changeover was previously completely reliable and is also afloat. My focus is on K + M, not on video. The VGA switch function I tested anyway and it works well. My impression is that the signal is slightly spongy. But does not bother me for my purposes.
In my opinion, a very solid price / performance ratio
