Hi,
I just got my, no final opinion yet. Some observations:
1) Gears is up and down and tilt but not for pan!
2) I have the lever lock, it works but I don't know if I like it
3) It seems to work as promised, if you lock a motion it is geared, unlock it and the camera moves freely,
Best regards
Erik
I was a bit worried about going from my old lever style Really Right to the Arca screw clamp, but I got used to the screw very quickly. It only takes 3 generous twists to open the jaws fully for drop-in/drop-out (as opposed to slide-in/slide-out).
After using it a bit that's maybe 2 or 3 seconds longer to mount the camera. So far, the rooms I've been shooting are OK with the wait 
I had planned to order the head clampless and adding a R.R.S. lever clamp, but that config wasn't available to me. When these come fully online I expect you'll be able to order it in the 4 configs just like the Arca ball heads. I could still switch out the clamp one day I guess. I doubt I will though.
Some will prefer the lever. I just wanted to say the knob's working fine for me after 3 years using a top-end lever clamp.
