Title: Fine ergonomics but stiff unresponsive keys
Review: I appreciate the effort that went into designing this keyboard. The layout is optimized for lengthy sessions without causing typical fatigue associated with standard keyboard layouts. Unfortunately, my unit has poor tactile response. They feel sticky and require considerable effort to press which makes typing a chose. I've had others that felt fine, but this one, for whatever reason has not delivered the expected level of quality. I gave it away to someone else who types much less than I and he hasn't complained.
Is the review positive or negative?
