Title: Great Idea, If It Actually Worked
Review: Bought this item after shopping around locally. It worked fine for about three weeks. Heart rate readings were accuate. After this time the readings would show wide deviations over very short periods (Drop from 130 to 80 then up to 90 then down to zero). The instruction book indicated the battery may be low. Purchased new battery but it still malfunctioned. All the other features work fine (clock, timer, alerts) but an accurate heart rate reading is the most essential part of the product. Currently trying to go through the process of sending the unit back for repair. Not worth the grief.
