the plastic tends to bow, and getting it from its collapsed state to its "ready" state is a bit of a PITA, but it works.
bear in mind the top opening is smallish, AND while it closes, it doesnt really like to "latch"
this would never be my first choice for a transport cage, but its a good thing to have when you need a second one, or a completely able to disinfect one!
because this one is entirely plastic, it can be completely disinfected- which is difficult with rattan, or canvas and wood
