I am absolutely thrilled with this Manfrotto 3-way head. My last one took nearly a decade to wear out, mostly due to abuse in salt water environments, and I had to have a new one.
This head works great with some of my larger lenses on board. The Nikon AI-S 300mm F2.8 and my Nikon AF-S 70-200mm F2.8 are both perfectly stable on this head. Friction controls are a nice addition, missing from my last head, and the collapsible levers get out us your way. Bubble levels pretty much exactly where you'd want them and a fantastic quick release system. It uses the same mount as previous pan-and-tilt Manfrotto head, so I can even use the old mounting plates.
I expect to get another 5-10 years out of this one.
