It's worth the $10, but could be better.

First off, overall it's great. The silicone skin fits perfectly. The mount allows for way better camera mounting and adjusting than the one it comes with. I am overall satisfied with the purchase.
The bad, the coupler that fits around the ball joint is not cut with precision so it's very jagged. Since, the ball joint itself is aluminum the coupler grinds into the ball and makes it harder and harder to adjust. I ended up taking some sandpaper and smoothing the ball out to help. To be fair the description does state it's hard to adjust, but I think they could solve this if they just made a more precise cut where the ball and coupler meet.
