I bought one of these early this past fall. I thought I would use it a lot over the winter so I could keep track of my heart rate, but did not because I took the other bike with the fenders instead of the bike with the BC-2006. Also, it was cold enough that I did not want to think about anything extra, like heart rate.

I wrote a pretty complete review of it at Amazon.com under my name (Philip J. Bohlken). In short, set up takes a little while and the manual is sometimes a little incomplete or confusing. In retrospect, I most appreciate the HRM, speedometer, odometer, and thermometer. The altitude indicator has not been very helpful to me.

It did seem to me that the BC-2006 uses batteries faster than I would like. The company was very good about inviting me to send the wheel sensor back to them. They checked it out and courteously replaced it at no cost. Winter came and I have not made any comparison rides since.

If you can, read my review at Amazon.com for more details.
