When I had read all the reviews I was have since written anything in uncertain several people that you have caught a Monday model which does not fly straight.
But if one reads the cardboard packaging times by standing there and how to fix it. By bending in one or the other direction you can see the Frisbee or also Aerobie ring called perfect set so that it flies straight.
This information is again in English it directly on the coupling ring itself.
So please first try to adjust before you send back the Frisbee.
For me, the Frisbee has perfect flight characteristics when thrown properly.
The throw must practice a little bit because it's a little bit different as with a normal Frisbee has no hole in the middle.
The price is ok.
Only the size of 33cm was nevertheless greater than imagined. It fits me bad in my backpack but so what, there is the slightly smaller version of the Aerobie ring with 25 cm diameter (then called Aerobie ring without Pro).
