I bought this for my daughter, who has two Holland Lop bunnies.  They previously had a two tier hutch but seem to like this one a lot more since the spend a lot of time outside the house enjoying the deck and light. They also jump the fence a lot too.  My husband assembled it and he isn't a patient man so the fact that I didn't hear him cussing tells me it wasn't too challenging.  It is very, very cute and less expensive than the one we had so a good value.
