Nice solid metal post and box. Instructions are terrible, poorly translated. They mention screws/bolts by their metric ID such as M8 for Metric 8 mm. BUT the parts are not labeled and there are several that can be mixed up.  The instructions fail to have even a simple line drawing of the parts, so you have to guess and try things. This added 30 min to assembly time. The anchor bolts are flimsier than I like, so I got some good solid ones from hardware store. The other thing that's missing is a simple template of the hole pattern for the base or even measurements of the hole placements. 
But once installed, it's a good solid box.
