These are the best flying discs money can buy. They're light and have a soft rubbery ring around the edge. They are easy to throw and they fly far when you wing them. We use these with our dogs, so the durability of our particular discs is probably affected quite a bit. About 2 months in and ours is definitely starting to look pretty beat. We have another one that we got almost a year ago--despite being warped and cracked, it still flies great, albeit a little wobbly. The dogs love these discs. We have purchased other soft discs made especially for dogs and if we take both types of discs out at the same time, our dogs will actually wait until we throw these before they'll commence playing. Definitely worth the money. I know I'll be back to replenish our stock.
