Assembly is super easy and directions were very clear! I guess i should have measured out more carefully as i was expecting this to be a tad bigger as i have a massive bunny lol. With an added pen connected to house it gives my bun the extra room so i am okay with that. She really seems to enjoy it so far. As far as quality....i have to rate this lower because the wood is very soft and if you have an aggressive chewer it wont last long. I see the wood also rotting fairly quick. The mesh wire that surrounds the cage is very thin and looks like it will also rot very quickly. If your looking for a house/run for a small rabbit or as an indoor place this is perfect but as a long term outdoor unit i would look further.
