I'm typing on a FreeStyle right now. My Kinesis Contour had to be repaired and I needing something with a bit of quality in it until I get the contour back. The keys are nothing like the contour, but they are not bad for membrane.. It actually sounds like there is a little switch in there. While there is a bit of mush, its nothing like the mush on the latest Logitech or Microsoft keyboards.
However, I am second guessing my purchase and wishing I had gone for a quality scissor switch keyboard, like the one on my thinkpad, only external to use until I get the contour back.
