As soon as I received this and began assembly it was obvious the product was poorly made.  The top was warped out of the box.  The general construction was poor.  All the panels were held to the frame using hot melt glue and were already apart; again out of the box.  Several on the slits on the bottom were cut too small and the clip wouldn't stay in.  I had to screw them in with hex screws.  After two days of light rain it got worse.  My bad was a result of not reading the reviews.  Had I done that it would never have been purchased.
