I've been using the same Garmin Soft Strap since 2015 for cycling (Edge 500 & 830), hiking & the gym (Fenix 3) and it has never had so much as one problem. I did change the battery last year just because I figured it was due even though it was still working great . I don't want or need BT so Ant+ isn't a problem. If it were to die tomorrow I wouldn't hesitate to replace it with an identical monitor.
