I used a Unicomp Quiet Touch Model M at my job for about 3 years - I still have it. After my BS Model M got vetoed by my office mates, I brought the 101-key Quiet Touch in and the noise it made was tolerated, as it was quieter than BS but still more noisy than any of the standard rubber domes in the office (Dell, HP cheapies).
Summary:
My all-time favorite layout is a 101-key ANSI model M, so I loved this keyboard's layout
It's makes more noise than most other rubber dome KBs, but it's still office compatible
Love the keycap profile - really great (subjectively)
The noise does however sound rattle-y, which makes it sound cheap
The feel of the rubber domes is not premium feeling, not even close
Overall, I was disappointed in how the domes felt so cheap, and I was also disappointed in how much noise the "quiet" touch put out. However I used it heavily for three years and it served it purpose - relatively inexpensive 101-key KB that I could use at work without driving my cubemates crazy.
