The person underneath who claims that it is "Too easy to throw, impossible to aim. Wonderful dog toy" is completely wrong, he must just be useless. Within the first 10 minutes of playing with it you can throw it with huge accuracy even in windy conditions. Even my girlfriend got the hang of it quickly even though she had never thrown a frisby or anything similar in her life!
You can easily keep this toy within your garden without any difficulty, but it's even more fun at a park/field where you can just throw it your hardest and really see what it can do.
Great summer toy for everyone of all ages.
