Worked well but not for long. I took this zipper and was very satisfied. the attachment point is freely rotatable and can be fixed in any position by pressing the locking lever. However, that attachment point broke in half the next day when installing the camera while snorkeling (luckily on a boat). As a result, the camera just fell off the mount completely. This was the second mission in two days, if it had happened in the water I would have lost the camera. Good idea, but the quality of the plastic parts still needs work.
