It has a really nice feel to it when typing fast, I can type a bit faster with it than I can with my Model M (I type slower on this than everything else) or my old membranes (which I have been using for years and I think they were pretty damn good compared to other membranes).
Comparison with membrane is due to the fact that I have only buckling springs and membranes to compare to. The feel is like a really smooth membrane with a different force curve. Membranes require all the force right at the start of the keystroke, making it pretty much impossible to half-press a button. On the Topres...its hard to describe, but it CAN be easily half pressed, if that says anything. When you compare the keys, the different weights are noticeable, but when actually typing, it just shows in speed i guess? As far as tactile feedback, not much really, all of its tactile feel seems to be caused by the force curve. Keys are pretty quiet, i believe they are quieter than my old membranes (though they were pretty loud for membranes).
I was actually looking for a clickly/tactile keyboard when I bought this and despite the fact that this doesn't fit the description of what I was looking for, I'm pleased with my purchase.
My poor description doesn't quite do it justice.
