Bought this house about a year ago and have been very pleased with it.  My only complaint is that the bars that stabilize the roof didn't fit into the tabs properly and have broken away.  However, this hasn't effected the performance.  My 60 lb pup still jumps up on the roof and lays there without causing damage.  He did manage to crew it up a little at first, but purchasing the replacement parts was very easy and reasonable.
