Review on Cateck Aluminum USB Switch Selector for 2 Computers Sharing 4 USB Devices - One-Button Swapping, Mouse, Scanner, Printer - USB 2.0 Peripheral Switcher Box Hub - Includes 2 Pack USB A to A Cable by Adam Gray

When I got this selector, it looked and worked fine, but with limitations. The selection had a significant lag, partly because of my screen, and also because the switching was very unreliable. HDMI connections were also very problematic. I must have switched between 5 different HDMI cables to get a combination that seems to stay connected. Not sure why, but the plug's too-flush design or possibly the internal electronics are to blame. Over time, the switch became more and more random until it was simply easier to switch cables by hand. .Despite the fact that I use this product very rarely (only on weekends), after a few months I had to give up.
