Review on POLAR H10 HR Sensor: Bluetooth Enabled, 🏋️ Black, M-XXL – Advanced Accuracy for Heart Rate Monitoring by Deva Raja (kamal) ᠌

It measures the pulse perfectly, I use it with the official app, there are many different workouts for every taste, it is very convenient as a personal trainer, it displays all heart rate zones depending on your training goal and health status, so you know when to speed up and when to slow down, a very comfortable strap doesn't fall off when running, I haven't tried swimming yet, though I dove into the water with it,
