They are pretty awesome. I put 3 of them on a Keycrhon Q3 with a set of Kinetic Labs Polycaps Code keycaps. They aren't QUITE the same green, but it's close. And these are in the upper right corner, far enough from the green escape and Enter keys for it to matter. I got Biohazard, Poison, and Radiation!
Repurposed the dreaded insert key

Very happy with these keycaps. Replaced the insert keycap with the radiation keycap on a couple keyboards, and created a hotkey as a quick way to put computer into hibernation mode.
Pimp your keyboard!

At last I got the "Panic" key I wanted so badly. So nice! I also the yellow "Radiation": very nice, too. Happy with the purchase, I am still trying to decide what is the right place for these keycaps, though!
