I had long wrestled with me, which of the many heavy-duty shelving (offered here) I should buy me. Ultimately, I chose here because of the recession for this. The packaging was very compact, the construction (profiles have to be just plugged together) very easy and absolutely foolproof. Assembly time about 20 minutes. I recommend gloves and NEN rubber mallet (but not mandatory - also goes everything by hand). Mostly you have to bend easily to another element to slide into the nipple to connect the elements. But this comes with a slight thumb pressure's play. All in all an absolute top product for this Price. Would buy again at any time. The existing reviews I can only say that there really no Sorcery is to build this rack. I've already two left hands but everything without problems and get one in no time together.
