In itself, this really is a good holder and thanks to its binding attachable to any handlebar. Unfortunately, the dismantling of the mobile phone holder (The staple dish or as they call it in the trade circle) can only be solved by force. The recesses for locking mounted in both directions of movement. So if you have geschaft it with a lot of power to unbind it may be that one has straight anchored the part in the opposite. Too bad.
Otherwise, a simpler binding for the handlebar would be desirable, since the holder is otherwise can solve only with Allen key (hand screw and a clamp lock eg). But was not as described - therefore no criticism but a hint, hint to the manufacturer ;-)
Overall, I'm satisfied with the part because I finally can go with my cell phone on outdoor cycling. the mobile phone is fastened securely and safely.
