Review on Maximize Your Performance with POLAR H9 Heart Rate Sensor by John Banks

I've been trying to find an acceptable solution for heart rate control when using a home elliptical. My previous Polar strap worked well with my Precor elliptical and @ 24 hour fitness equipment. Then the heart monitor function on my Precor became erratic and unreliable even though the device was still performing other functions such as raising and lowering. I've tried different types of third-party fitness trackers and bluetooth bracelets that claim to connect to multiple fitness apps, but end up getting them all back. I've used Polar gear for runs in the past but found that the watch/bracelet combo didn't provide reliable performance. I'm happy to report that this device works great with the Polar Express Fitness app right out of the box. instantly connected to my android devices. I used a feature in the app itself to connect - it was instant, smooth, and reliable. I use the simplest of the many features available in this app and get a lot of summary information at the end of my workout. I can definitely recommend this strap/app for the heart rate monitoring feature - I would be very optimistic about its other/my myriad of features. The app is key to performance and the strap is key to connectivity.
