Review on COOSPO Bluetooth & ANT+ Heart Rate Monitor Armband - Optical HRM Sensor, Waterproof IP67, Fitness Tracker Armband Compatible with Zwift, Wahoo Fitness, Endomondo, Peloton - Includes One Extra Free Armband by Kantrel Tunstill

Update: After 7 months the device stopped working. As the device began to fail, I noticed the inconsistency of the readings and the intermittent loss of communication. ***************************** ********** ***** ****** Original Review: For use with MapMy Fitness and Run, iSmooth Run, and Nike Run Club. Should work with applications that use Bluetooth or ANT. If using Bluetooth, pair through the Fitness app and not through the Bluetooth settings. Accurate readings. Turns on and off quickly. Use 3 times a week for 45-60 minutes per session. Charged once since ownership. The charger connects magnetically for a secure connection. Comes with two strong Velcro straps that keep the monitor in place and comfortable. Previously had a Scosche HRM handguard. They are more expensive and the straps don't have good velcro.
