They used a dirt cheap switch for the middle button, so no doubt it will fail again. I ended up adapting to never using middle button after it became unusable. I'm still not using it even on my new mouse (not Corsair) out of habit.

Yes, but you will invalidate the warranty. You also have to be careful not to crack the casing of damage the ribbon cables inside, which will most likely need to be disconnected to properly separate the casing. After that, you will also need to know what you're doing and whether or not you can come up with a custom fix. You will most likely need a torx screwdriver. They're the screws used on the M65 and I assume they used them in your mouse too.

My LUX came with some grippy spares, but they're WASD fascist. Do you have any grippy spares that are generic (a basic shape instead of a font) so we can use them for any key? I've seen some third party ones on Amazon, but I have no idea on their quality. Plus, I like the spare caps (shape and feel, just not the font regulations). This post is more about the recognition of cursor key users.
