Super unfortunately supplied with lattice defects

The grid is good and also very easy to build a. Everything is self-explanatory. The stability is good. Many possibilities to adjust in height and in width.
Unfortunately, and for the first at the goods I ordered on Amazon has these significant shortcomings both scratch and abrasion marks on plastic and are very clearly and not just slightly.
two of the supplied plastic locking screws put only the set screws in the sleeve, the screw heads were completely canceled.
Unfortunately, I had to organize an exchange because of the planned trip any time.

Without these shortcomings, I would have given all five stars
