Product Description:
HEART RATE MONITOR,

Rating : - Worked great then gives false readings
For the first 3 months, the strap worked great. It's much more comfortable than the standard garmin heart rate monitor. Now it consistently gives false, high readings. This morning I averaged 220 bpm on a run that really was around 150 bpm. I've tried wetting the strap contacts and using heart rate gel. The Garmin forum has an extensive discussion of the issue under the topic heading "Heart Rate Monitor gives me erroneous readings" or "Premium heart rate monitor (soft strap)". Basically, the thing is a piece of junk and I would recommend that you stick with the normal garmin monitor and not the premium version. I've used the cheaper model for 2 years with absolutely no problems.
