Purchased these keycaps to go on my fullsize Ducky One2. So far I haven't had any issues with legibility or keeping them clean. Night visibility is also fantastic. My only complaint is circumstantial, I have also purchased the add on caps with this set and after installing the numpad section with the alternate caps I decided to go back to the included ones. While removing the caps, two of my switches (Cherry MX Silent Red) decided to come with them. Two switches ripped in half. Luckily I had replacement switches handy. Unfortunate I had to void my board's warranty on the first day but it is what it is. Don't let this sway your purchasing decision just a likely one off situation you may want to be aware of.
