Great buy.  Comes ready to assemble....bring your patience and mechanical skills...tools help too.  Scary when you open the box,  but worth the patience and effort. Actually, not as difficult to assemble as it looks at first.   Not a heavy duty structure, but very acceptable for small to medium birds. Lots of openings to access the interior.  Be sure to latch the openings properly or you may get an escapee.  Rolls easily for underneath access, cleans easily.  Food and water trays are plastic and fragile.  Be prepared to replace them when they break.  Excellent aviary let's you enjoy watching your birds have fun.  Good price.
