Title: Intermittent action
Review: I purchased the HRM even though a few of the reviews complained about intermittent function under different conditions. I also found that I couldn't rely on its readings when engaged in high intensity activity. I assumed that the lower price was due to the limited funtionality but found that it also had some reliability issues- one doesn't want erronious reading on a HRM. The device worked fine when walking, biking or using the elliptical up to about 135-140 bps. Above that intensity it started to double the reading and jump all around and then quit altogether. I could manually check my HR and find that it was where it shold be. I could also compare it to the HRM on the bike and elliptical machine. Running seemed to be the worst, and I think it might be trying to count footfalls when running fast. I don't know the funtion of this device but if it is sensitive to that type of shock it could be the issue. I returned it and am still looking for a more reliable device.
