Review on HRM Pro Premium Real Time Dynamics Batteries by Joseph Harkins

I have a non-Garmin heart rate strap that works great, although the HRM-Pro integrates perfectly with my Garmin 945 so buying for made sense to me. The additional metrics on my running data that the strap provides are also helpful. UPDATE, just recently this failed. I registered it with Garmin and replacing it was as easy as emailing Garmin. Garmin shipped my new monitor and shipping the old one to Garmin was free. The 5 star rating for the product remains unchanged and Garmin has provided me with fantastic customer service. If I have another crash my rating will change. LAST UPDATE, Garmin's replacement failed almost exactly like the original. Very disappointing. Started with erratic and/or high heart rates, then had trouble recognizing my Garmin 945 and the Garmin app on my Android phone. Maybe I am, although I have no idea how it will be. I have had an inexpensive but very reliable heart rate monitor/belt for over 2 years at a bargain price and I am using it again. 11pm at Revain By the way. I ended up with built in Garmin straps/monitors.
