I have two, large-breed dogs who are hard on their toys. This frisbee is a tad on the heavy side, but held up better than the fabric ones I had been buying. Under normal use, my pups go through about one frisbee per month. This frisbee made it three months, which I am happy with. The whistle feature is a little on the gimmicky/disappointing side, but still pretty cool. I think the whistling impressed the humans at the dog park more than my dogs...All-in-all this frisbee is very durable, I like the feel of the material, and most importantly, my dogs loved it to death until they finally tore it in half. I will buy another, and would recommend to anyone with medium or large dogs (it's a bit heavy for small pooches).
