UGREEN KVM Switch HDMI 4K@60Hz, USB 3.0 Switch, 4 Port USB Switcher [1 USB C and 3 USB A Port] Sharing Keyboard Mouse Hard Drives Printer, KVM Switch 2 PC 1 Monitor with 2 USB Cables and 2 HDMI Cable

Works with the Razer Death Adder mouse which my previous KVM switch didn't (I don't have the RGB lights on). Note - you don't need to use the USB C power (and no cable comes with it) - I understand power is only needed if you add certain things like a hard drive on but basic keyboards and mice should be fine.The only downside is my old KVM worked with keyboard shortcuts so you didn't need to press a separate button. The button is ok though and is about 1m length.The main unit has 2 small blue LED lights to tell you what you have selected - the button does not.

Works with Logitech bolt which fails with many KVM. Screen switches fast, Surface laptop tends to lag when switched many times, works perfectly with other devices on 4k@60Hz, with a HUB and bolt receiver, have keyboard, mouse, drawing board, mic with headphones and webcam on. No issues. Small form factor, great reliability.

This is exactly what I was looking for. Works really well and switches flawlessly between my desktop and laptop top with a flick of a button. There is a toggle button on the top but also comes with a breakout button for convenience. Comes with all the cables to connect two computers to the screen. Only reason for 4 starts is it dosent cone with a wall adapter or a usb C cable to power it up. Having said that it's not required atleast not in my case and works fine without the need for external power. Finish is really good and connectors feel sturdy with good spacing. Definitely well worth it. Connected one keyboard and a mouse via dongle which works for both computers flawlessly.

So good I've also set this up in my girlfriends office!

Been using this KVM for almost a month now and it's been a rollercoaster (not a good one). Some days it works fine, some days it causes nothing but problems.Off the bat I realised all the HDMI and USB A to B cables were quite short, the length should be fine if you have your PC, laptop and monitor on a desk, but if you use a standing desk with your PC not on the desk then the cables are way too short, I ended up having to buy a 2M Ugreen HDMI cable to ensure the compatibility was there and they would be long enough, however I could not find any official Ugreen USB A to B cables, so I had to buy a different brand.When it arrived it worked fine, but now for some reason both the Ugreen and other USB A to B cable either work intermittently or stop working altogether. I've plugged a USB C cable into the KVM from my PC for power, but I don't even know if that is helping.It's worth noting that I've been using a HDMI to USB C to connect my laptop, whilst that has caused some issues with connectivity, it usually sorts itself out after a couple disconnects and switching between my PC and laptop through the KVM.The manual provided doesn't have much info regarding troubleshooting, just 5 basic checks. I haven't tried contacting the "After-sales" they said to in the manual, however judging from other reviews it doesn't seem to be too hopeful.If you want relatively budget, easy to use and works out of the box KVM, this is NOT the KVM to buy, the only positive thing I can say about this KVM is that the build quality is nice and the button is half decent.However, if you're willing to basically do troubleshooting and diagnosis frequently, to figure out the correct configuration and you can grab this KVM discounted (as I did), it's not bad for the price.

I bought it so I can switch my webcam between personal pc and work laptop. Works like a charm. I tested all USB ports. They are all working fine. I also tested plugging in my ultrawide screen 3440x1440 monitor. It ran at 50fps (meant to 120fps) and also 12ms (meant to be 7.2). Afaik, this is expected, need to shell out more money for better fps in high resolution. All in all, all the ports work. It's a small switch suitable for my modest needs.

Absolutely perfect for my home office set up. I have one iMac mini and one mini PC connected to one screen and can switch between the two with a click of a button without having to use separate keyboards. Very pleased.

Pretty good but not perfect. The switch remote control is irritating in that it doesn’t have a light to indicate which computer it’s switched to so you have to guess which isn’t ideal but it’s liveable.But more crucially at least once a day after a period of inactivity, returning back to my desk and trying to use one of my computers just gives me a black screen with my monitor not reading any input from the KVM. I have to then unplug and replug in the power on my monitor to make it wake up.Note: I am using it with a Mac Studio and a MacBook Pro plugged into power and closed lid / clamshell mode, and so the closed laptop lid could potentially be partly to blame for this, that and the fact that Macs are notoriously bad for EDID management.
