The joints are surprisingly solid. They are easy to move, yet they *really* stay where you put them. They do not slip. The phone feels secure. Very very lightweight, too.
The phone bumper is bigger than my last one, which I do not prefer. However, it is easy to take on and off if you want to.
Enclosed in the box is a clip with a screw camera mount. It slides into the "U" shaped holster. Also stable feeling if you use a regular camera, too. The clip is small and flat, so you could leave it always attached to the camera without noticing.
I use it daily to lift my phone out of the way of possible spills while I cook; to raise the camera for FaceTime chats; to direct the speaker for radio; to hold my phone more naturally (as a fist) when reading the news on my phone.
