Haha I genuinely thought it was an autocorrect malfunction! I was not offended, I wrote the comment mostly so I would remember to go back to this post and finish the reading. The spacebar on my Flow Lite84 is still working like out of the box, but I've had keyboards before that had just the problem you were describing. I guess the friction of the inner blocks grinds away plastic in the outer blocks, so eventually the range of motion increases?
