Review on POLAR H10 HR Sensor: Bluetooth Enabled, 🏋️ Black, M-XXL – Advanced Accuracy for Heart Rate Monitoring by Bong Cha ᠌

Although I believe that the gray ones may have ended and put what was in the hope that a person who waits a week will not make a return to wait another week, although someone might it seems that I find fault, but still I want to get exactly what you order, the store decided that with the choice of color I can go to hell ordered gray came black I don't care. Got advantages: a decent strap connects to the phone's Polar Bit software rapidly. Cons of it: I believe the clasp to be extremely flimsy and am unsure of its durability.
