We are very dissastisfied with this product.  Hinge pieces were missing and holes weren't drilled.  We had to go to hardware store to find the appropriate pieces and then drill holes.  In addition, the velcro adhesive that holds the top down has already fallen off.  We are in the process of buying new velcro and adhering with a strong, industrial glue.  For as expensive as this was, we are very disappointed.  WE would have returned the item if it wasn't so large and so difficult to get back in the box
