After using this keyboard for a month, the stock keycaps, which are roughly textured, have been wrecking my fingertips, my entire left hands is peeling and gross from gaming. If you have sensitive hands change out your keycaps. My fingers are shiny with new callouses
feastofvioletdang, that's intense. I type 8 hours a day and game on rough pbt keycaps and haven't ever had this happen.
I'd be kind of worried about RSI and tendon issues if you're working it that hard. Might want to take a look at your technique and modify it a little.
