Great cantilever especially for the price.  I read other reviews so I knew that I would need 18 x 18 pavers to hold it down.  Gave 4 stars because the instructions should have been more clear about what size weights or pavers should be used.  At first our pavers were too thick but my husband is pretty handy and made it work.  Also, consider whether it needs to be moved a lot.   Mine does not, so for the price....this works great.
