Very nice and sturdy. Good spring loaded locks that have to be held to open and close the door. This means it's more predator proof than others that don't have spring locks. The only complaint is that is takes a few hours to assemble, you need at least two people, and there were some confusion which side is right side out. The upside is instructions were mostly clear, all parts are labeled, and extra screws provided in case you lose one. Only had this for a short time so can't comment on how it holds up.
