Eric Olofsonwrote a review of GoPro Surf Mount on July 21, 2016
Familiarity: I've used it several times
I actually picked these up to mount on the wall in opposite corners of my band's practice space. Obviously, not really their intended purpose, but with all the noise and vibration going on in the small room, they've stayed right in place. Surfing, boating, skating, snow shredding, you name it... I can see these being great for many different activities.
