This shed has two fundamental key problems:  1. The quality of materials is very poor.   A large percentage of the screws strip so easily due to the soft plastic and poor hole construction.  It leaves the shed weak and compromised.  2.  The instructions are horrendous!  The pictures don't look anything like the actual pieces you're working with and the orientation is backwards in many cases.  Worse, large details are left out, resulting you having to undue work and go back since it didn't cover a key step.  I would not buy this shed again.
