I wanted to find a decent, secure top handle for the Weebill S that was cheaper than another competitor. This seems reasonable and secure enough to get the job done. My only nitpick is that the cold shoe is off center at the top. Good that there are no moving parts apart from the locking mechanism. Good grip, the color complements the red lines of the Weebill S. What is button 2 for? just to tighten the lock? it's very easy.
