Arrived with some black marks on them and sides were coming undone, but a replacement was sent immediately.  Love the modern look and the fact that it's see-through.  My puppy also likes to be able to see me when he's in there.  I'm not sure how long this will last because it is a bit flimsy, but it works for now.  (My puppy is 3lbs by the way, should be 6-7 lbs full grown).  I wouldn't recommend this for bigger puppies/large dogs.
