This disk is the REAL DEAL!  I am amazed with the perfect weight and balance of the Aerobie and its flying characteristics. I haven't really played with a fresbe since the original professional fresbe back in the late 70's, but I have a high energy dog who needs almost daily running and playing.  This disk is simply the best I could have hoped for.  It flies almost effortlessly and is easy to throw straight and level. I can easily get a 40 yard flight out of it and the dog just loves going after it and catching it in flight.  He just loves to jump high and snag it out of the air.  I highly recommend the Aerobie disk!!!
