Garmin HRM-Dual Heart Rate Monitor Bundle with 5 Extra Batteries (6 Items) - Accurate Chest Strap for Running, Cycling & Fitness Tracking

Muy buen monitor para montar y muy precisomuy buena compra lo que necesitabaThe strap gets the job done. I'm replacing mine because I over tightened the screws and broke the housing. I recommend this strap.However, I take issue with the battery last up to 3.5 years verbiage.I typically run 40 minutes a run, 4 time a week. Over a year, I go through about 2 or 3 batteries. Not bad, but not exactly 1 per 3.5 years either.I realize they state "up to" and most likely the estimate is based on a hour per outing.It feels a bit sketchy is all.I can’t get it to stay connected to my peloton bike. Doesn’t workSyncs easily with my Garmin device, seems to be accurate, I’ve been using for a few weeks and battery still works. Biotech to monitor yee ol ticker. Take it from one ol geezer it’s a fun deviceNever worked right with my rower, and this model is not compatible with the Garmin app. Could not be more disappointed with the purchase.Love this a use it with my Peloton. The reading seems to be consistent and accurate and I love that you can unsnap the sensor or wash the band in the washing machine.Love this and happy it works with the Peloton app.
