Assembly "instructions" could be better.  Be sure to remove protective film from panels prior to assembly or you'll regret it.  Screw holes did not line up very well on top panels and  gaps were prevalent in panel overlaps.  Don't assume interior will be weatherproof.  After assembly which included adding a 3/4" thick stranded panel for the floor I am ok with the final product as it will be located under a deck in a semi-protected areal
