I wanted a heart rate monitor in the form of a watch so I could use it not only for cycling but for running. This one fit the bill. The alarm is barely audible. After the first 5 months or so I started to get zero heart rate readings and the error message "Check heart rate monitor strap.
Able to use it on the bike as well as for running
Can't hear the alarm Reliability issues with the strap/transmitter/receiver
