Review on The Ultimate Garmin HRM-Tri Heart Rate Monitor: Track Your Performance with Precision by Todd Mamat

Ideal for cycling and running. I haven't had a chance to use it in the water yet. Update, it's been 1 year and 2 months since I bought this HRM. On a recent boot, the device told me the battery was low. I found it weird as I had it replaced maybe 2 months ago and went for a bike ride the next day. apparently the last run was all he had left in the battery. After changing the battery, it was not registered in my watch or in my cycle computer. I took the battery off my cadence sensor and tried it. still does not work. I understand that this device has to endure a lot of sweat and exercise, but seriously. 1 year and 2 months or 287 hours and 23 minutes of use, I have many other Garmin devices and this one let me down at first.
