The shed is not 5x3. It’s smaller measuring outside pieces and interior space which should be 5x3 !. It took 3 hours to put together and I hired a contractor & his helper. Since no foundation (even some treated plywood to nail on would help) and it’s not heavy aluminum, you can easily lift up & steal what’s inside .. the exterior lock is a joke due to this but also that lock slide loop is very small so no good (less cuttable) locks can be used. It’s manufactured in China and return has a 50/50 chance to make it back plus the huge expense. Stuck with this overpriced low quality shed. I have to pay contractor another 100$ to put wood on bottom.  I shld of used that to get a larger & well made shed.  Very disappointed. I would recommend not buying shed.
