Surprisingly good quality.  Very sturdy metal, with a weatherproof dipped paint covering that looks like it will last well.  All components present (& 1 spare bolt and nuts).  Very straightforward to assemble; took about 30 minutes. 

If I was being hypercritical I would point out that the cheap spanner included is insufficient as to to tighten the bolts that have separate nuts you need to have two 10 mm spanners not one.  But 99% of the people who buy one of these will probably have a couple of 10 mm spanners available to them.
