Have I bought this greenhouse for the very reasonable price and had therefore expected also not particularly high quality. When building then the surprise, the quality for the price is more than convincing. Of course you should not expect a professional greenhouse, but perfectly adequate for every hobby gardener. The assembly instructions are for those who can an IKEA shelf injury free assemble, understandable and well illustrated, however, reckon on to build a good six hours. Have the greenhouse built for the most part alone together, just needed to assemble the four sides for 10 minutes, the help of my wife. A little tip: The discs are to be glued with silicone and are then fixed until the brackets, that makes that whole more stable and significantly less prone to wind. From me, there are still five star and a strong buy recommendation.
