It’s a great size, but the vinyl is really thin and the zipper is super cheap as well (you have to fully unzip before you zip up (no halfway zips) or the zipper teeth on the opposite end open up.  I bought this one to use an an addition to another pet pen that I already own so I would have one upstairs and one downstairs.  This one was much cheaper than what I had paid for my other one, but you get what you pay for I guess.  I have a small toy breed puppy and this does not feel sturdy at all - I’m sure it’s only a matter of time before he chews his way out.
