Clicker review eInstruction Response on Mac OSX

eInstruction is a company making clickers for audience response in lectures and seminars. This page is a review of the hardware clicker CPS Pulse and the accompanying software Response v6.71 (12/2012). The software appears to be mostly in Java and thus runs on Windows, Mac, and Linux. I'm testing on a Mac, so the comments may not extend to the other run-time environments.
