Yes! It got a nice solid feel, takes a good amount of force and make a pretty loud sound -- a bit hollow sounding because of the fairly large plastic case it's in.
I don't like the keyboard layout at all though, but then again being an RPN calculator was not it's primary mission.

This was such an innovative calculator: 5-level RPN, 3 microcontrollers, many power supply options, choice of semi-permanent keyboard overlays, not to mention all the navigation, fuel and timer functions. And, of course if was available per-assembled or as a kit.
