I have. Don't ask me why but I my friends and I were at a driving range (none of us really golf. We were hung over and needed an activity that wasn't too strenuous) We decided to get some artsy shots of golfing and set the GoPro 6 feet in front of the tee. Hoping the ball would shoot over it, creating a cool effect. I stepped up to the tee, channelling my inner Tiger and swung furiously. I then heard a loud *crack*.
The ball went straight into the GoPro, instantly smashing the case into pieces. The GoPro never turned on again. It was under warranty so we got a new one though.
Also, SD card was damaged by the impact so there was no footage to share, causing some to not believe this story.
Party for sorrying.
