Review on 🖥️ 2 Port HDMI KVM Switcher Box - 4K 60Hz, USB, Share 2 Computers with one Keyboard Mouse and Monitor, Supports 4K (3840x2160), UHD, HDMI2.0b HDCP2.2, Wireless Keyboard and Mouse Compatibility by Preston Molden

Build quality doesn't feel cheap. It's durable yet lightweight. I had no problems with it and it works as expected. There is no increase in latency when using a mouse, keyboard or monitor. I connected SDAC/AMP at as high a bitrate as my computer will allow and there is no stuttering. I haven't tested all the possibilities of 4K/60Hz/HDR (I have 1080p monitors) but I've used a Koopman HDMI switcher (another product from them) and it handles 4K/60Hz/HDR just fine. Your reputation has always been at the top. This allows you to use 3 USB ports and it does not have to be the same mouse and keyboard. In my case I have a mouse and a SDAC/AMP, then a 3rd stick slot. Chances are you can plug in a USB hub if you need more ports and it will handle it. No external power supply is required, which is a big plus as I don't have extra outlets. It comes with two USB cables to connect two computers. You'll have to use your own HDMI cables, but they're cheap and you probably have 30 dusty cables in your closet. My ONLY complaint, if you can call it that, is that the two cables that come with the unit are a rich blue color. Not a big deal, but I would have preferred black as it's standard and blends well. However, he grew up with me. Overall, what you see is what you get, which is a pleasant surprise when it comes to tech/computer hardware. No damages, crashes, driver or software installation, stuttering or problems. It's literally plug and play. If it looks like what you're looking for, rest assured it does what it says on the tin. This is a great purchase.
