Review on 🖥️ 4-Port USB Switch Selector: AIMOS USB KVM Switcher for Sharing 4 Computers and 4 USB Devices with One-Button Swapping - Ideal for Mouse, Keyboard, Printer, Scanner (Includes 4 USB Cables) by Darren Munajj

Pros: The box is solidly built and I liked the ability to have separate buttons to switch directly to this computer. As long as I didn't try to switch ports while the computer was on, it worked. Installation: I connected three computers: Desktop, Surface Laptop and Xbox Series XI using good quality shielded USB cables (not the unnecessary cables that came with the box). I have four devices connected: a mouse, a keyboard, a USB network adapter, and an Xbox 360 controller. Conclusion: I would not trust this device. Something about its design produces strange results. It is possible that this will cause an inrush current when all four devices are plugged in at the same time. It is possible that this will cause power failures in connected devices (e.g. because the device is not powered when switching and rapidly transitions from +V --> 0 --> +V). Whatever the reason, it's not worth the headache. That's a shame, since there are so few ways to toggle multiple devices across four PCs, and even fewer that have a button for each target PC. But it just doesn't work reliably enough.
