The company must have read the past complaints.  My box arrive in good condition and better protected than most boxes.  The insides were protected with bubble wrap and Styrofoam.  I had a complete set of instructions which were well written and included  pictures for each step.  The wheel casters are the best I've seen on any cage or piece of furniture that I have assembled.  The tray is fine.  I had a flight cage (no longer being made) with 2 trays the same size.  They were made out of metal and were so heavy I hated pulling them out.  While placing the various bird accouterments, I did notice 2 bars were slightly bent.  They are not noticeable at a distance > 5 inches.  I did not bother straightening them.  It took me 1.5 hours to put the cage together by myself.  The overweight 50 year old lady who put hers together in 30 minutes deserves an award.  If you are working alone you will want something (tape, twist ties, etc) to help hold the upper side parts of the cage  while securing the top.  I do not like the door closing mechanisms., but that is easy to work around.  There are a lot of doors on this cage, 2 large in the front and 3 smaller on each side.  I will use this cage for finches and it seam perfect.  .
