I have a Magic Trackpad for the Mac and I use this cheap mouse connected through the KVM for both Mac and pc
I actually use the $7 mouse, I have a $60 mouse but prefer the simple wired mouse as I have a USB hub located on my desk (no batteries or charging.)
i have an amazon basics keyboard that is perfectly satisfactory. expect the same from this.
I'm not sure about quality, but this seems to be pretty close to a classic design.
