The crate literally just pops open and one twist and it folds up.
I took off one star only because it's a little tight for my larger dog, who is about 60 lbs. I would get the XL crate if he were to be in it for long periods (overnight). He can lay down and stand up, but not turn comfortably. The smaller dog (about 40 lbs) fits well and seems quite comfortable in it.
It doesn't collapse, even when she lays to one side so I don't have to prop it up at all.
All in all, very good value for the money.

Pros: soft and comfortable, easy set up and take down.
Cons: would not use for a dog over 50 lbs.
