I recently got a Sunwayfoto DDH-03 clamp.  There is a slight design flaw with this product.  The panning action is very smooth until I put a plate in the clamp and tighten it.  As the clamp is tightened the moving side of the jaw cants upward.  This is what happens when you push two 45 degree pieces like that.  I can see it in clamps I have from other manufacturers as well.  The problem with the Sunway is that there is enough movement that the bottom of the jaw begins to interfere with the panning action.  I can back off the clamping pressure and relieve the problem, but using the clamp as I normally do always causes the problem.  All they needed to do was machine the bottom of that jaw with a little more space on the bottom.  I'm actually considering taking the clamp apart and doing the surgery myself.
