Title: Worked for a month only
Review: Bummer. Worked well for the first few weeks - comfortable, realistic heart rates. Now it's showing wrong heart rates - e.g. 42 bpm after 30 min. of running, or bpm's in the 60's. It doesn't matter whether I'm playing tennis outside, working out in a gym... Simply doesn't work :o(((
