I purchased this crate for my 6 month old puppy.  She will be a 50 pounder, at least, when fully grown.  She needed alot more room than her previous crate provided and I was looking for something that was attractive, as well.  This crate fits the bill and is very easy to use with its 4 doors. It's easy to move around with the wheels and is lightweight.  It is easy to set up and fold down for travel, etc.
I am very pleased with this purchase and would recommend it highly.
If I had to find any fault with it, I would suggest to the manufacturer that they use metal clasps as opposed to the plastic ones.  So far so good, but, I do worry that the plastic might break.
