Product seems made of quality, durable materials.  The directions to assemble were as unclear as only an engineer could make them.  Seriously the pictures were minuscule with few close up views.  

How about putting a few stickers with messages like "Left side, Right side, bottom" etc?  I'm pretty good at assembly/making things and I got the thing almost 100% assembled before I realized that the sides, which are almost identical, were reversed.  So It sits outside waiting for clement weather to re assemble the whole thing.
