I have not yet made much use of this new accessory for my tripod, but I am expecting that it will allow me to make sharper images of the action subjects I enjoy shooting, e.g., wild birds, air shows, sports car races, etc. The head is well made, but I guess I will need to buy a longer mounting plate in order to get my camera/lens combination (Canon 7D Mark II w/ battery grip and 100-400 mm lens) to balance. It probably would balance without the weight of the battery grip, but I like the additional shooting time it provides since I shoot these subjects on high-speed continuous most of the time. The rotation about the gimbal head's horizontal axis is very smooth, and so is the rotation about the vertical axis of my tripod's ball head - the two work well together. At this point, all is as expected and I'm looking forward to making extensive use of this new piece of gear in the near future.
