These things are awesome and they are MUCH cheaper on amazon than in the stores where i have seen them.  if you haven't used one of these rings before, they fly FOREVER and are a lot of fun.  There is a slight learning curve to throwing them, but once you get it down you will have a blast.  We are on 3rd one (1 broke and 1 was lost) and still get hours of enjoyment throwing this guy around the park
