Reply to How to install chroma caps? I want to get my glow on!

The new glow in the dark faders look so sick, but before I buy them I just want to know how easy it is to install. Is it just something you put over your original fader? I have a traktor s2 and I don't remember reading anywhere that the knobs and faders can be removed. If it's really simple I have my credit card right here and am ready to do work!
