Heads up if you want the 35xx pro, the G350 which I'm assuming has the exact same shell is built weird.
The board is only screwed in at the bottom half of the shell, so it kinda seesaws
I think because of this they used a slightly taller pivot on the dpad but the same membrane and pad shape of the other xx devices, resulting in an insanely sensitive mess. Fixable thankfully
I didn't have to cover anywhere near this much of the pads on my 35xx+

I had to get quite aggressive with my g350
