ATTENTION! Fa. Voelkner counts NOT return shipping or postage costs. Have twice unsuccessfully the return postage costs trying to get back. Wrong! It is not responded or the e-mails are not answered. The VCM-ceiling mount TDH 4 had already been repeatedly exchanged. There were several screws loose in box. The three 10mm plastic dowels can not keep the heavy VCM Deckenhalterung of 10kg in my opinion. Is fastened only by three screws on the ceiling! If even a 42 inch TV will then drangehängt, I'm not sure if that does not fall off at some point. As determined does not pay the damage insurance! Previous owner must have tried the Deckenhalterungung to assemble. Thread the attachment was filthy and zerkratz. The whole ceiling mount was stained with lubricating grease. So the best of intentions, even if you turning a blind both eyes, you could this dirty, used Deckenhalterung not keep. The return by the previous owner has not been tested with security to be complete. It is an outrage of Fa. Voelker not refund the shipping cost back. The fault lies with the seller - not the customer. I will buy in future only directly from Amazon! Discontinued Market Place! At Amazon they had the exchanged immediately without further ado.
