The transport box is stable and well finished. The On / degradation is not a problem even without instructions. The various openings (top, front, side) can be well adapted to the respective premises the box. Our Owtscharka Hybrid loves his "cave" and pulls them even the beloved couch watching what I did not expect. In addition worth mentioning is the soft liner that works well insulated, but we also prefer another blanket to put in the box. I would recommend this transport box with a clear conscience.
