Just a rant. I can't believe Garmin produced a new HRM and has the opportunity to correct the poor design of the plastic connector and doesn't. Maybe it just me but I've always had issues with the strap coming undone while running. I end up sewing a stitch in the fabric, so the plastic connector is snugger. Looks like they added a little "bump" in the plastic so they knew this was an issue, but it still fails.
