Summary: I have used it for about 6-8 months now. It works fine and is comfortable. I do fine the buttons on the watch a little difficult to use and the screen is not all that bright. But, it does what I want and accuracy compared to an monitor reader on my bike is bang on.
Summary: I own an older version of Polar (cyclometer/cadence/HR). For the past three years I ended up living in the hospital more than at home. When I finally could resume my riding I found my instrument display fading. I returned it to Polar for servicing.
Summary: I bought this heart rate monitor probably 2-years ago and still use it to this day. It is easy to use, seemingly accurate and the battery lasts for more than a year at a time. The strap is still in brand new condition, even after many washings. Very happy with this product.
