This took us approximately 30 minutes to put together, give or take 10 minutes. The provided instructions weren't helpful but provided a link to full instructions with pictures that you would be mostly lost without. It is structurally stable and spins easily. The one thing we were surprised about were the gaps that are in it. I'm sure it's by design but it makes for opening it very interesting since you are bombarded by trillions of fruit flies. Great for the money.
