great  quality.  great  price.  very  poor  instructions,  but  simple  to  install.  notice  the  color  and  size  of  the  plastic  bolts.  two  different  sizes.  the  short  ones  go  into  the  vertical  inside  poles.  Get  that  correct  and  the  rest  is  simple.  Except  the  last  part  on  the  roof  (holes  didn't  match up,  so  I  used  GE  silicon  and alls  well).
