I was skeptical of buying a greenhouse online. The product came well packaged with all the parts. I can’t say if it was difficult to put together since I hired someone to do it. It took the person about 5-6 to finish. The product is not heavy at all. I can lift the thing with one hand. I’m afraid it might fly away in high winds so it definitely needs to be anchored down. I wish this product came with something to anchor it with. Unfortunately you have to buy that separately. This green house is aesthetically pleasing. It is perfect for few of our plants to keep them safe from harsh winter weather.
