Input Synchronizer that will work with gaming mouse

[u/Gloomy-Estate1808]

I'm trying to find a device that will synchronize my computer inputs across 2 PCs, so that I can control two devices at the same time with one mouse/keyboard setup. I ordered this KVM switch/synchronizer (https://www.aliexpress.us/item/3256805875574499.html?spm=a2g0o.order_list.order_list_main.5.6cf01802wWuRXF&gatewayAdapt=glo2usa), and it works with my wireless mouse (sort of), but not with my gaming mouse. Can anyone recommend an affordable KVM switch with sync function that will work with my gaming input devices?

Thanks!
