Finally a large crate with clips! Assembly and disassembly with clips can be done in a heartbeat instead of the lengthy hassle of bolts and wingnuts (they are included however). The wheels slide on and off in seconds and the handles are a great feature. My only complaint is that the ventilation could be better. I wouldn't use this crate in a hot climate unless extra holes were drilled along the bottom half. The interior of the crate fits a 36" long crate mat. Our puppy is only 45 lbs (but long bodied) and fits this crate perfectly. This crate size seems best suited for a medium-sized dog. Overall we are very happy with our purchase. It shipped earlier than expected which was a bonus, and everything looked new and well packaged.
