I have a Keychron K3 Pro keyboard that can be programmed with VIA and I’m more than happy with it.
My mouse is a VAXEE Outset Wireless. This doesn’t need any software to change DPI / polling rate etc. All of it can be done by pressing buttons on the underside of the mouse. It works very reliably.
I know it’s not feasible, but if a lot of males would just use the apps that are know to report to US authorities and input data, that most likely will raise a alarms, they would have to deal with heaps of false-positives and it would obscure the real data.
