I bought this tripod from Adorama (through Amazon) and the box arrived damaged. The tripod seemed to be in good shape except for the center column. The column itself was fine, but the internal screw holding the low angle adaptor was bent and the adaptor wobbles out when it is released. When the low angle adaptor is fully seated in the column, it's firmly in place. I sent it back to get a replacement and the second one has the same "defect." Is this normal for this tripod? Other than this small problem, the tripod works great: has 4 leg angles to achieve low angle shots, center column is removeable and can be re-mounted horizontally, and overall it's very well built.
