A fine and well-functioning heart rate monitor. It worked immediately after pairing, and the heart rate remains consistently stable when measured. Hopefully, it will continue to work this way.

The strap of the HR monitor is super comfortable and the sensor is really accurate. They both turn on when they sense motion so I believe the battery will last a long time. Unbeatable for the price and works perfectly with the Geoid cc700
