Got the keycaps for my G.ProX keyboard. A good fit in general, although I did have to sand down the left-hand edge of the left-side CTRL key a tiny bit as it would catch against the side of the keyboard body and get stuck down as a result. LED shine-through is not as bright as the ABS keycaps that come standard with the G.ProX, and you don't have the media control writing on the function keys, but they're decent regardless. And since it comes with the standard size spacebar, CTRL, CAPSLOCK and right-hand SHIFT keys too, as well as numeric keypad keys, it can likely be used on most full-size keyboards as well.
Very good quality, little different font and size on some keys but no problem at all!
