Very good stuff, probably holds 30 years. The preparation and the pilot holes are a disaster! I'm really technically gifted, but if the holes are pre-drilled wrong, efforts are being made from! Above all I can for this money, expect properly pre-drilled and easily zusamenzusetzende parts, otherwise I can also pick up a cheap product. An insolence of Pinolino and sad that such a great brand is not able to remedy these errors. I'm not the first to denounce the.
