I bought 2 of small greenhouses. Convinced had me the yellow clips (clearly visible on the product photo), with which you can connect the hood to the cup ... so there is no displacement of the cover is possible. Unfortunately the two supplied me greenhouses this yellow clips have not exactly. Pity! Had I known that, I would have opted for a cheaper option! For this reason, only 4 stars. Otherwise, the two greenhouses make a good impression and stabilized materials. The plastic cover, as well as the floor could be a bit stabilier. I have an older version of these greenhouses, which is much stronger and firmer and thicker the material here. Unfortunately, probably saved anywhere! The air vents are easy to open and close. The greenhouses can be stacked one above the other by the well fitted under the floor feet, so that a Belüstung still should be possible. Another advantage is certainly the side-mounted holes in the cover, which prevent the soil or seed starts to get moldy. So is always a slight ventilation given. I want in the two greenhouses cacti and am curious. The delivery of the greenhouses was fast, despite the adverse weather, so how the usual ISR Amazon. But again, kudos!
