The shelf is divided into two parts in height; the connection of the vertical rods is initially extremely resilient; but if everything is set up, it is relatively good. Anyone planning to store heavy in the upper part, should fix the upper vertical rods with screws on the wall.
The installation manual is a joke, but it is not complicated anyway. The tabs on the middle board-support one must bend himself, are doing anywhere.
The installation itself goes really fast. The instructions say that you should bend the tabs, if necessary with a screwdriver, if it does not fit so well; the metal is so thin that you can do that too conveniently by hand (wearing gloves!). A few times that will be necessary, but only lasts a few seconds.
Basically, I am satisfied; because of the sharp edges and the manual 1 point deduction.
