Review: Not perfect but supports the capabilities I need - I bought this KVM to support testing of multiple computers from a single kbd/mse. I wanted one that supported 4K@60hz, but couldn't find one that was reasonably priced. This unit supports 4K@30hz, not optimal but good enough. So far, the unit has worked well, though I have only tested with a 1080p TV so far. As another reviewer indicated, I do have some problems with the switch. Unlike that reviewer, mine works fine; it sometime takes two presses before it actually switches and you have to switch fairly slowly. I only docked a single star for this inconvenience, however.
Review: Only Half Bad - It worked well for 2 computers, with a 3rd computer, plugged in I could not get the switch to work at all. I didn't try different combinations, so not sure if it was due to the 3rd computer being a Mac laptop or if only 2 ports work. For the first 2 computers, it did work nicely.

Received product, but the included power adapter has the wrong size plug and I was unable to find another plug that fits the KVM to try it out.
