Fast delivery, frame feels quite sturdy, thin panels around the thickness of lemonade bottles but they have survived strong wind, rain and hailstones over the last few weeks since we built it. The shelves in the shelf kit are two small plastic shelves that clip onto the frame so not worth the extra £40 when you can get cheaper wire racking elsewhere. As expected it needed two people to put together but the instructions were OK. Overall though I don't think you could get a better greenhouse for the price. Seedlings are doing very well. If you're looking to take a step up from growing on a windowledge but don't have the funds for a 'proper' greenhouse, this is perfect. I'm really glad we got it.
