After trying a number of KVMs, this first one worked for me and was a lot cheaper than some others. Build quality is great, runs fast and does exactly what I need it to. What I liked the most is that it has a total of 4 USB ports that can be shared. For my gaming keyboard, which takes up two USBs, this was very important as I can share my keyboard and mouse and then use the last port to connect to my monitor's USB hub to then share even more. I wish I could find this one first instead of wasting time on other KVMs.
