After 3 months of use, my Garmin Instinct has started making a loud, metallic, rattling sound when it's vibrating. I sounds like something has come loose. It's surprising, given that it's never been dropped, or banged against anything. The only activities it's seen are short runs (3 to 4 times a week), and gym workouts (couple times a week). Very disappointed, esp. given that the Instinct has been marketed as being a "rugged outdoor watch."
I've contacted Garmin support, but have yet to hear back.
Has anyone else have similar experience?
