If you still think the hardware is pretty good, you haven’t been using their newer hardware.
I think I wrote a comment about this recently, but their newest mouse with a layout I like (G604) was made with terrible soft rubber that is practically designed to disintegrate with use. All their mouse switches are also short life crappy switches that stop working relatively quickly.
Soldering new switches into the G604 is an absolute PITA because it was designed by people who didn’t care for repair. Still doable, just annoying. I just wish the rubber was replaced with the grippy hard textured plastic they used a few years earlier.
At least you only need to use the software at first when you’re setting things up.
