I finished the slickrock trail in Moab, Utah this past weekend and wanted to measure my progress with my Forerunner 205. I was a little apprehensive about taking my GPS because of the roughness of the trail and the possibility of my Garmin popping out and either breaking or getting lost. 3 hours later the GPS is still there and the Quick Release did its job even through a rather rough crash. And even though my elbow has a nasty scrape from the sandstone, the Garmin looks as good as ever. I would definitely recommend this Quick Release to anyone wanting to attach their Forerunner 205/305 to their bikes.
