Review on Oregon Scientific IHM8000 Heart Rate Monitor Watch with Calorie Counter - Stay Fit and Track Your Progress! by Michele Denzer

You will not get a good heart rate. I bought one and then returned it as it can't handle a decent heart rate. They replaced him and I gave him a second chance. It did not work. I tried customer service. They told me to take it apart and remove the battery, let it sit for ten minutes and that should fix the problem. A The 4 small (really small) screws on the back are different lengths with no indication of which size goes in which hole, making it difficult to change them, and B it didn't make much of a difference. Just to give you an idea, after 20 minutes of moderate walking my heart rate was 110 bpm, but after 4 minutes of intense jumping rope my heart rate was 86 bpm.
