I can vouch for the buttons on the RG35XXSP turning to shit surprisingly quickly. It's a launch unit.

Played a shitton of Super Metroid and Aria of Sorrow on it, primarily using just the Y, B, and A buttons. You can see they're really sunken in compared to the X button.
I can still play Super Metroid on this thing but it requires too much physical force to be reliable and comfortable.

I wanna open it up sometime to replace and/or fix the buttons and membranes but haven't gotten around to it.
It's apparently less of an issue with the newer units that revised the buttons to be less clicky, but that was only for new colors that I didn't want. I love the transparent blue shell and wanted to keep that.
