I think mine's broken. It's started giving really odd results every now and again. I replaced the battery, cleaned it and tightened it and it was OK for a few months but it's doing it again now. Today it said I'd hit my max HR as I ran down a slope onto the beach and a few days ago, it consistently recorded a run at precisely the same pace as the previous run but at 10 beats higher.
What are people's experiences, do they break down like this? Seems like it's just not making a good connection anymore.
