First time user of mechanical keyboard. The keys are smaller than I am used to but I don't seem to have as much trouble with typos as most others do. If you want a compact keyboard then the k65 is the way to go. Did a lot of research and the rapidfire version has newer hardware than the normal k65 so the lights don't flicker at 16m color. Because there is no Lux version (basically newer K65 with no flicker issue), I went with the rapidfire but no regrets.
