Complicated, cumbersome and partly inappropriate

The structure is described quite complicated. It assembles parts to make them again having to break down in the next picture of the description. Not quite conclusively the description and confusing! Big annoyance is the attachment of the glass plates with the further move forward in my part on the left rail and faulty to 3mm holes. In addition, missing 3 nuts. Thus, the top plate can not and fix the lower plate only after tens of experiments and back and bend the rails, this voltage is applied to the plate. For the price not so great thought! I hope with regard to the fixing can be somewhat Rules!
