Have had 4, yes 4, HRM strap monitors now in past 3+ years. Had to buy 2 replacements. Garmin supplied 1 only. Its wrong that these things don't last at least 3 years or so.
Now 4th one stopped after 13 months. "Jared" at customer support is non responsive. I asked for this to be handled. No response. Horrible quality. Have used Garmin on plane, boat, marathons and ironmans. I have an expectation of quality but Garmin is failing..........
