マイダ レイ 5 This is the real thing. A Frisbee is a WWI bi-plane, a PiperCub; the Aerobie is an F-16. The little one is OK for kids (maybe 5yrs old, 6 and up) or perhaps to learn or warm up before using the Pro or if you don't have much space. The Pro requires a lot of space, 70/100 meters (or more if you've got some wind) depending on your age, fitness and expertise. You can 'play' with it in less space but not near trees or water or unsuspecting people. There is nothing quite like two or three people working an Aerobie Pro. The Aerobie isn't about competition, there is no agony of defeat though success and failure are a part ofan Aerobie 'session'. Check it out and remember, real pros only catch with one hand.
