Overall I was pleased with the cover. Good quality zipper. It actually takes to grow well until you hear a "click" and once in place it does not move. Very useful the gear inside the pocket to compensate the lack of thickness. So that GSM remains in place against the plastic cover. There are also two gear which are delivered at the same attachment of the handlebar. Only negative for me is the fragility of the fastening system (clamping screw) on the handlebar. I tighten / loosen 2-3 times to find the ideal possition and the clamping screw turn already crazy. I can no longer tighten securely. Fortunately the cover still remains in place when I ride.
