I was having trouble getting reliable 4K over my KVM. My monitor already has multiple inputs, so I've switched to just using them for video. I just needed something to switch keyboard and mouse back and forth. They've been working great for a few months now. I also like that there are no hotkeys as they can interfere with things like vmware or remote session software when working from home. Just a simple button on the device to switch. If I could change something it would be to have all the ports on one side. Whatever the case, you have cables coming out either side, so cable management is an issue.
