Sturdy, love that the pan is metal and has 2 doors. Contains my 4lb chihuahua puppy well!  Since it is not plastic or canvas, she can't chew her way out or chew anything on the crate! I followed a review from amazon and turned the divider horizontal to create 2nd floor so she nas more room. Now I just need hubby to build stairs so she can get up there.  : )  I will post pics on amazon when complete.
