I have found it pretty easy to make small adjustments. I don't have much experiance with any other ball heads, as my regular tripod is a 3-way and my monpod has it's own quick-release. So I don't have much to compare with, except for those I just mentioned. When I make adjustments, I hold the camera with my right hand using the same hand position as if I were ready to shot a picture. While holding the camera with my right hand I loosen the ball level with my left hand, and guide the camera to wherever I want it, then tighten again with my left hand. I've found that the camera stays pretty much where it is until I'm ready to move it, if that makes any sense. Bottom line is that I've never had any situations where adjusting the camera was an issue.
The only complaint I have (and it's a small one) is with the bag. I wish it was just a little bit bigger around near the opening. And I wish the arm strap was a just little longer. I'm a bit on the husky side, so it's probably just the right length for most other folks.
Let me know if you have any other questions.
