I have always wanted one of these "Z" type of heads and this one is everything I want it to be! Very well made and works flawlessly. One thing that really impressed me is that it comes with a removable threaded insert (see picture) that allows it to be installed on a regular 1/4" screw mount or the larger threaded mount that my Bogen tripod has. It has a couple bubble levels on it so that I always can get true level even if my tripod is not level. The little tightening knobs work well and they are able to be moved out of the way by pulling them away from the head and twisted to one side or another once it is tightened down, they have springs inside them so they snap back into place once you move them out of the way. Very easy to use and works extremely smoothly when moving the platforms or the base for getting panoramic side to side shots. when its all collapsed down, it has a very small profile to it and takes up hardly any space. This head allows me to get my camera into just about any position I can think of and the locks hold it in place securely. I am in love with this head, and it will probably be the only tripod head I will ever use now.
