Review on High-Performance 4-Port USB3.0 HDMI KVM Switch with CEC, SPDIF 5.1 Extractor, and USB Peripheral Hub - Ideal for Keyboard, Wireless Mouse, Printer, Scanner, Windows, 4K 60Hz HDR HDMI Auto Switch 4x1 with IR Remote, IR Extender, and Mic Input by Louis Asok

When a mouse is plugged into the dedicated mouse port, the vertical movement of the mouse is really limited - best described as movement on the physical surface == vertical movement on the screen. Horizontal Movement - Move a few inches across the entire screen. Virtually useless. When the mouse is plugged into regular USB ports everything is fine, but that means I can't use the switch. Same problem with or without a wired mouse. The keyboard is also buggy: the keys "stick" and repeat frequently with my Logitech wireless keyboard. The physical keyboard seems ok, but then again. doesn't work with my normal gear. Port Switching: You need to switch the port twice to connect the USB. Never does the first time. Overall very buggy and weird. Great form factor
