Bj and Emily Chauvinwrote a review of GoPro The Tool Thumb Screw Wrench on December 22, 2014
Familiarity: I've used it several times
This is just a knick knack, sometimes its easier to use this to loosen or snug the nut mounts with this little wrench. Mainly its nice when you have gloves on. The bottle opener is always a plus too. I mainly use it as a zipper pull.
