This crate works well and I really like the sliding door.  The reason I take off 1/2 of a star is that we nearly broke the thing trying to get it assembled.  For some reason it was stuck and it took my husband 15 minutes to get it unstuck.  The directions were no help....maybe I got a faulty one or something.   The only other thing is that if you pull the door up too far, it comes off of the track and it is a PITA to get back in, as you have to turn the crate on it's side and insert it from the bottom...not an easy feat if it is in a tight corner of the laundry room as ours is.  Other than that it has been a good purchase - especially for the price.
