I'm new to this type of tripod head. I'm finding it a little difficult to understand when to use the main tension knob and when to use the fine tuning knob. My other issue is that it swivels 90 degrees in only one direction. I didn't think I would care about this, but it's a little inconvenient. Overall, though, I'm happy with it. It seems to be well constructed.

The ball-head itself is made really well. Feels very solid with with 5D MkII with 70-200 2.8L mounted. The quick release lock button (orange button) is terrible. It does not operate smoothly as the rest of the product. Very difficult to deal with in cold temperatures. The plate that attaches to the lens/camera uses a screw head. I can't believe they are getting away with this. You can't be searching for quarter coin in the middle of the night at a remote site, if suddenly you need to change the plate to a different equipment. The knobs are well made and makes for a precise adjustment. But the knobs will feel like they are secure, but they usually are not. One needs to really tighten the knob to make the position secure. Coming from a Manfrotto ball-head, these quirks are real annoyance. But if you can see past these issue, it's a great head for the price.
