In the winter I use the monitor to spin, run, and workout indoors. It is exactly what I need to get the information that I want; however in a crowded spinning class, there are chances of 'cross talk' between other people with HR monitors.
It's an excellent product for the price.
I had another heart rate monitor that had so many features I didn't know how to work it. If you want a cheap and easy to use one without all the bells and whistles this is the one.
