Review on Enhance Your Cycling Setup with the K-Edge Stem Mount for Garmin Computer - Choose Adjustable or Fixed Options by Shane Jenkins

Now my Garmin 520 has suddenly disappeared from its mount several times. To be honest I can't explain this phenomenon, yes I ride mountain bikes but it's not my hands knocking it down, it's not my knees or legs because I think I'll feel it and indeed if itself my knees or legs around me are lifting trunk, something is wrong. My only explanation is that the damn thing springs out on its own, probably because the bike hits the ground. Anyway, I'm very annoyed and will start using a leash.
