What is the opinion of Reddit about the
Cateck USB 3.0 Aluminum Sharing Switch Selector 4 Port 2 Computers Peripheral Switcher Adapter Hub for PC, Printer, Scanner, Mouse, Keyboard with One Button Swapping and 2 Pack USB 3.0 Male Cable?

There are probably better KVM switches out there but this hub does the job for me.

For video I just switch between inputs on my monitor. It does this really quickly when I sleep or shutdown either machine.

There shouldn’t be any audio delay though a usb switch I have used many and never noticed any. The on I would recommend is this one I’ve been using it for many years and it’s hasn’t failed on me.

I use this one: https://www.amazon.com/gp/product/B07TV34NSD/

I have no had no issue with it for 15 months now, daily use.
