Good value, vertical movements are gentle contrast to the horizontal that they are hard and cause some jerks, perhaps in the long head will grind. Nevertheless, I remain pleased with this acquisition, which allowed me to make stable shots with my little HD camcorder during our last vacation. I also tested with my D700 + + 25mm grip, but it seems that the whole is a bit heavy, mainly to block the device in vertical position, the tightening is not perfect.
