I am giving it 4 stars because of the price.  I got it on sale, if I paid full price, I probably would've given it only 3 stars.  One of the bracket's holes were too big for the bolts so we found a couple bolts that we had that fit so we can finish putting it together.  Also trying to put the outer ring together and into the clasps was not an easy job.  Some connections were lose and some were very tight and you really have to squeeze it together to complete the ring. Then you had to try to keep it together while trying put into the clasps.  It took me a number of attempts and a few expletives.
