Easy to assemble, but it's hard to see the numbers on the poles for positioning. I bought this not to use as a green house but to store and dry out my wood flooring. I had a house fire and the flooring was ruined and had to be replaced. I will be repurposed the flooring once it's dried out. The plastic top is not just thin plastic, the greenhouse even in cold weather stays warm, while the suns out. I would recommend it.
