Ciao, seems I read in the information you provided that one has to push a button in order to get the heart rate readout. My Polar is not working right now so I thought I'd get a cheapy-type HRM, but then found out I have to push a button in order to get a readout. I may be spoiled, but I don't want to have to push a button. I want a constant readout . . so will definitely get my Polar fixed.
