Title: this product is terrible
Review: When I first ordered this product it did not work at all. The screen was completely blank. I sent for a new one, which appeared to work initially. However after I started exercising with it I realized that it was indicating my heart rate was extremely high. During one run it said my heart rate was over 200. Since I am still alive, clearly the monitor was not functioning properly.
