It's fine. I was disappointed in the actual cover, which is basically the whole greenhouse- it came with a tear on a seam right out of the box, and a tie came off the seam immediately.  I am going to try to contact the mfctr for a replacement but don't have a lot of hope. 
The 'shelves' are ridiculously thin and flimsy, and buckle even with a seedling tray or 1 plant on it. Honestly i'm disappointed but it unfortunately had the features I was looking for, and now it's a part of the home.
