Title: Good, for a while...
Review: I have had this head for several years and recently only used it rarely. The concept behind this is sound, though the execution is lacking. If you want to support even a moderate weight camera and lens the tension has to be set nearly to the maximum. When it's set this way repositioning the head is very difficult. Even when tightened down all the way, if the head is set at an angle it tends to fall forward. It worked pretty well for the first year or so but is essentially useless now.
