Hope this isn't a dumb question, but. . . Are GMK mini-spacebars the real thing with a rounded spacebar profile, or are they just. . . blank Shift keys? I've tried those before, but the sharp edge is not comfortable to bash with the side of my thumb.
I am pretty dedicated to my split spacebar layouts, and if GMK are now turning out "real" 2.25u and 2.75u spacebars, I'll jump on that.
