The positives:. Very easy to assemble and made of quality materials. Decent value for the money.
The negatives:  The design makes it inherently wobbly (even when set in concrete).  The issue is that the base is comprised of two pieces.  The bottom piece has tapered ends that slide into the top piece, with no fasteners.  As a result, it is not stable no matter how hard you shove the two parts of the base together. The two-piece design is not indicated in the product description or pictures. If I had been aware of this, I would have bought something more expensive.
