FYI -
If you are using the X-grip, the goofy rubber tether they give you is there for a reason
Use it
Don't ask me how I know :evil
Yep, I've done a lot of miles and it's never slipped out ..... Until
Mine did not come with said goofy piece...
Photo?
I do know using it as a camera phone mount sucks for stable video platform.
That's weird, I never had a problem with mine either until last Saturday. Got gas at Nemo and lost the phone at 30 mph on Vanocker Road. Stopped turned around, a Harley almost ran it over, picked it up, it was fine.
