Is it normal for WSAD keys to fade so quick?

[borley]

Hi i got the QPAD MK-50 keyboard last week, first mechanical i have owned, anyway i have been using since Thursday and i wouldn't say i ahve used for more than 4 hours a day.
But the WASD keys look like they are dirty so tried cleaning with cotton wool bud but no change are they fading already?

Admit it, you use hand cream don't you?

Well i look at a lot of adult sites
Nah i wouldn't return it if i was realy bothered i could repleace with the 4 orange keys you get.
The keyboard was £65 free next day postage because i linked my forum account and i got a free physical copy of Max Payne 3 which i sold on the auction place for £17 so after there fees £15 so keyboard for £50, not bad
