After we took our dog for years in a normal transport box, he has torn this recently. So quickly had a new forth! But as simple as that is not at all if the car does not increase bottom. Then we came across this one and have unceremoniously ordered. For the price you get nothing like what is tailored to our vehicle. They fit perfectly in the car trunk. The 7 cm increase described herein, serves the rounding behind the seats to compensate. All in all a top transport box. Oh for the clattering emergency the foam rubber is intended that came in the package.
