Zisc flies well and is very pliable, which is great for catching, but the toy is not as indestructible as advertised. Our 23lb golden doodle chewed holes in it within a matter of minutes. We also purchased the Hurley bone toy, however, and that makes an excellent chew toy. She has been working on that one for over a month and it doesn't have a mark on it. So, we get the Zisc out only for play time to avoid her destroying it. Good value and will last longer than the nylon "frisbee" we had previously.
