I already have two of the frisbee, a medium size (about 25cm) and large 33cm. In the end we use little if ever the small and the great is ideal for fun long distance. My previous large ring aeroboe died for several reasons left in the sun, the plastic cracked, and if it is not kept flat and he curls even slightly, say goodbye to its effectiveness. So I bought one, convinced. I recommend. If not for the average distance tricks: aerobic "full" 25cm, it's great!
