The box is easy to assemble, easy to fold together. However, it is very easy - what have to do with the natural pliability. This causes the dog has to get out fairly quickly, depending on intelligence or boredom as he can with the box around the flat balls. : D Looks funny but causes not quite what it should.
For the first transport in the car and the first few weeks in her new home I find the box ok. For proper travel I see the metal frame Soft Kennel but clear advantage.
