The hr monitor works great and is comfortable. My issue is with the software (polar flow and polar beat) that works with it. You can go to the polar web app and plan your workouts. Those workouts will show up on the diary in Flow iOS app.

I had an old HRT that had a "watch" I had to wear. This ties right into my phone and the Polar app is very good (although it records distance on my bike different than Strava). It's a very responsive strap and it's great to have to push yourself in different workouts.

I had the samest, problem as other reviewers -- this gadget is impressive at first, then it stops working. I replaced the battery twice with no results. And I can't get the company to respond to my requests for support via any medium. It's too bad because while it works, it's perfect.

I have been using my H10 for several weeks to conduct morning orthostatic tests. The wireless connection (I'm using bluetooth) has been fast and reliable. The strap is comfortable and picks up my hearth rhythm very fast.

Simple and effective. I purchased this to get a more accurate HR reading on my Apple Watch while skate skiing and uphill ski skinning, both of which have arm movements that could cause cadence errors in wrist-based monitor. It has worked very well for this purpose.

I was getting poor quality readings with my other BT HRM so I bought the PolarH10. I measure my heart rate variability in the morning with the H10 and my Android phone and get great signal strength.

Bought what I thought would be the best. Wanted to use it on different exercise equipment but also wanted to monitor my HR with the app. Works on equipment but can’t use the app without divulging all my personal info.

So far this HR strap works well. It is far more comfortable than the 4iiii which I purchased last year and already stopped working.

I was very happy with this device until the recent firmware update. After updating, it no longer works with my Technogym treadmill. Technical support has been unresponsive and not helpful, and there’s no way to roll back to the previous firmware.

Works really well with the Polar Beat app. But both the unit and the app seem a bit buggy - as in needing to reinstall the app from time to time and take the battery out of the unit and re-pair. The web summary of training is excellent.
