The box fits the description and is very convenient and sufficiently stable. The size fits to our Golden Retriever mixed breed with a shoulder height of 50cm. I use it mainly in a station wagon in the luggage compartment for transport. As for durability, I can not say anything, since I use the box for just over a week. Saturated the original soil liner I use a normal ceiling. It's never happened that our dog had done his business in the box. The cotton blanket seems to be easier to wash. The only drawback, and therefore only 4 stars: Would not even want a Velcro fastener on the roof, so you can stow the darkening not only, but also the grid. At least I have not yet figured out how that should work. Place the grid easily upwards. Description I have found none.
