The product is a useful tool, for sure. I h...ave it paired with the suunto 9 watch. The reason it does not get 5 stars is simply because I would like to see suunto incorporate gps along with the heart rate monitor to avoid having to wear both during certain activities.

This smart sensor is good if you wa...nt to connect it through your phone or tablet to the Suunto Movescount app. It does not work with gym equipment. It will not transmit heart rate data to your treadmill, bike, or elliptical. It works well with the iPhone but the Movescount app does not sync properly at the time of this review. Maybe a bug fix from Suunto will correct that. You may need to use it with another app like Sports-Tracker until the fix. The sensor does not work with older sports watches. The manufacturer says it will sync with watches as old as the M5, but I have not been able to connect it even to my T6D which is much, much newer and smarter. Conclusion, buy this if you need it for a smartphone app or if you have an Ambit 3 or newer watch. Otherwise look for the older sensor that can actually connect to your gym equipment and control it for speed and elevation. Polar H7 may be a better alternative if you do not care much about using it with a sports watch.

The conductive chest band is fragile. Any electric... contact failure will lead to inaccurate reading (unusually high, such as >200 bpm) or even disconnection of this HRM, probably because the device counting the noise for HR calculation, and it automatically switch-off if it cannot acquire countable electric signals. Replacing the chest band perfectly fix the problem, but no one will be willing to do this every half a year.

This watch fits comfortably and reads quickly on both m...y Suunto 9 Baro, and my iPhone 11. I'm 5'7" and about 145 and did not need to adjust the strap out of the box. It stays put very well during running and circuit workouts. My only complaint is that while connected to the iPhone, the sensor is unable to connect to the watch. Definitely would recommend this if you're looking to track HRV or peaks and averages during exercise.
