Significant weaknesses in processing

I must honestly confess that I have quite shaken after assembly upside down. What has ever bothered me that the beams were bolted to the unit with IKEA moderate coarse thread screws directly into the plastic housing. From a reasonable thread no trace. In addition, the small rear wheels make a rather baggy impression that the housing twists the curves go strong. The front wheels are more stable, but eggs significantly (in practice probably care, but quality looks now times different).

But the real hammer is the handling. The unit must have been designed for extremely diminutive people. For a child of ten, the working height should be optimal, but even for a normal-sized people, it no longer fits. With my 1.90 m I would have stooped to run after the appliance. Since the angular displacement of the beam does not help - which is designed so lousy the rest that it holds only if one additionally inserted into the holder such as an old rag and so fixed the spar. You remember what I wrote above already to the plastic screw?

Well, at the disaster I have packed the unit immediately and sent back. I can therefore say absolutely nothing about the function.
