My new Polar H9

This replaced a much older Polar model that gave up after many years of use. That one did not have a replaceable battery, this one does. I look forward to many more years of reliable use.

Outstanding device!!!

Perfect for using with Polar Flow app, but what I bought it for was to use with the Elite HRV app, and it works with it flawlessly. I didn't expect to be able to also connect it with my Apple Watch 7, but it connects easily, and I am able to use my Apple Watch to track my workouts, while using the h9's heart rate, which is much more reliable than my Apple Watch one. My Apple Watch has a tendency to lose HR for a minute once in a while, now that problem is gone. I literally love this thing!

Good Quality Heart Sensor

I've used Polar products for decades. Dependable and used to have great customer service. Their customer service note leaves something to be desired but their products are reliable.
