Title: HR-100C Operates well if you wet your skin first.
Review: I tried the HR-100 and according to instructions tried to wet the electrodes (non-porous). This did not work. I wet my skin and then put it on and it worked well. The instructions provide you with the alternative of using a conductive gel, which I did not try.
