Appearance solid, smooth and accurate settings. But ball not exactly designed for quick shots or reports or for backpackers without Sherpa, but my alta pro 263AT that supports it is also a good weight. But for those looking for quality and stability is a very good choice. My 7D equipped with its 18-135 zoom pique over the nose without necessitating a tightening madman. Corresponds to my need. I removed one star because the concept of fast VEGA PHOTO is not exactly that on which Amazon has accustomed us. I stayed over a week with a foot without a head.
