The shelf I have only been 2 years in the cellar and it still does the job. The building was finished quickly and easily. Quality defects I can not speak. The wood is perfectly fine, but a high-quality finish you can not expect at the price. Rough spots here and there, but do not need much effort and then see properly out. If you like, the wood may subsequently extra editing with oil. When assembled, the shelf is very easy, therefore, the impression may arise that it is very unstable. With bottles inserted, things look different.
My conclusion: screwing, bottled pure, holding out what. Value for the little money definitely.
