Fast delivery, good packaging, but the most important for me is the perfect size for dog and car. The box is ideal for dogs of size L, with long sheepdogs I would recommend one size larger. Also important: The box fits perfectly in the new BMW Touring 5'er type F11 and the Porsche Cayenne type 957. In normal driving conditions, the box is fixed in the trunk and not slip. The setup was very easy, you can build the box also alone. In the manual is a response time of 1-2 hours, but everyone can read and know how around you have to hold a screwdriver, which also creates in 30 minutes. The side panels are pre-assembled, you put the cross struts in the side panels, then the panels clean, another side part on top and with 8 screws (Allen key included) tighten, done.
