Finally - after three years of anger, I have taken down the thing from my tripod and replaced with a pistol grip. The Manfrotto is so big that it fits in any pocket tripod - either remains the zipper on a lever and looks out one or unscrews the lever, which is not exactly convenient and comfortable. To truly lock the head, you have to tighten the screws properly - with at least as much power as you need them to solve a gun head. The adapter plate must be screwed with a coin - so I always change in the camera bag. The snap lock which receives grabs the plate or not he snapped - that it can be solved and sometimes not again ... I dutzene times pinched my fingers sometimes ...
Advantages of this head here are the three spirit levels and the full adjustment and the suspension that prevents too fast folding down with an attached lens Langer and their striking the tripod or elsewhere.
For me, the 808 is perhaps more for video recordings for use - or to auction it ... let's see.
