I really like my keyboard. However, this evening I thought I'd change out the key caps with a more contoured, more concave, set from a used-to-own Leopold TKL. The Leopold key caps are simple ABS; however, the difference, improvement, in my keyboard's feel is marked. I did this on my lone Cherry KB: Corsair K65/MX Red. And I just gave away a set of new Filco key cap--figures. The stock key caps on the K65 are somewhat concave, but not as concave as those off the old Leopold TKL. My keyboard went from one I really liked to one that is incredible because of contoured key caps. I should mention that Leopold's TKL key caps have a bit of gritty surface that, for me, enhances the feel of each cap. I'm sure the surface texture will smooth out with use.
With MX Red switches, accidental key strikes is a common complaint. I find that I'm making far fewer accidental key strikes with these contour caps. I'm accustomed to MX Reds, and the feel is so much improved with contoured key caps. If I'm repeating myself, mea culpa, but this is making such a difference in a key switch that I liked before making the key-cap change. For me, this is a discovery. I thought that I preferred the feel of flatter key caps, like on a standard CMQFR. However, I was pleasantly surprised with the improvement in accuracy and speed with the contoured key caps. They feel as if they center and align one's fingertips, which stands to reason, far better than flatter key caps (why isn't key cap a compound word; same for key switch?). There may be many on GH who have made this discovery; for me, this is a first.
Question for GH: I'm sure GH knows the answer to this question: Are WASD's key caps concave like, say, Filco's or those on Leopold's TKLs? Thanks, GH.
