Although I have to agree with the other parts are not burred, but that in no way interfere with the establishment. If you can lift 5kg, you can plug together these parts. The structure is simple and it does the job. It is very suitable for the cellar and even contributes more than is described in the Produktbeschriebung. Of course you should not test how far you can go, but maybe ^^ #. Meanwhile, I have now ordered the 3rd shelf for my cellar shack. Because even though it may not be the super duper strong quality, and considers it is definitely in the price / performance ratio is miles ahead with this.
