Rating: - Nice, but you can't replace the transmitter battery
I have used this monitor for about a month now for running, Spinning and indoor workouts. It has performed flawlessly. It would get 5 stars except that the transmitter (the half of the monitor that you wear around your chest) does not allow you to replace the battery. Buying(...) I suppose it is a disposable consumer product.

I gave this HR monitor to my parents as a gift. They are in their early 60s and shifting to a healthier lifestyle, including regular exercise.They both like the Polar and find it very helpful. My Mom uses it at the health center, where it is compatible with the exercise machines (a health center trainer showed her how to use it to get the right workout). She is generally not good with technical things, but she said she found the main function - the heart rate monitor - very easy to use. My Dad uses it when he goes cycling outdoors and he really enjoys the technical functions - it is his new "toy".

The monitor broke shortly after a year, and it has only a one year warranty. It worked well enough while it worked. But sometimes it would give my heart rate as 225. I don't think so!
