We bought this crate to replace an older crate which was not foldable.  It works fine and is somewhat lighter in weight, but our 80 lb. lab gets rather anxious when left alone and he could probably pull the ends open with his teeth if he got lucky.  (With our previous crate he squeezed through when the bottom door latch was not secure, then managed to pull open a tilt-open double hung window and jump through a screen to to find some people.)  We added a bunch of snap-locks around the ends to ensure that he can't get loose.  The lighter weight makes-up for the design.  If our dog was not so determined to get out, I would rate this crate 5 stars.

The two doors are really nice.  In the house we use the end and in the SUV we use the side.
