10/10. I have a cattle dog that loves chasing disks. She catches them in flight and mauls them once caught. This disk, like the Jawz, has survived her attempts to kill it after being caught. So far, 10 outings and no punctures. So I'm really very pleased with the material's ability to survive her attacks.
But a disk has another purpose, and this one lives up to that too.
I love a disk that flies straight and far and true, even in wind. Most Frisbees turn over in the wind and crash to the ground. This disk doesn't do that. It holds its flight path, and when thrown into the wind, it hangs there, while the dog waits underneath for the kill.
This disk is up there with the heavy-duty Jawz disk, perhaps even slightly better in performance.
At close to half the price, it's worth it, for both the dog, and me :-)
