Mounted on my Manfrotto tripod - 055CXPRO3, this set gives me a perfect stability for my camera, and that is reassuring. Very easy to use, we appreciate these different functions: rotating 360 degrees, double spirit level, 2 locking levels for the unit tilted, the ball resistance level. 4 stars and not 5 for its weight. I have more memory, but I feel perfectly when I weigh, especially when the door feels. So not very convenient for travel.
