They drop really fast and are not good if your dog takes off and chews on them. Our dog ripped big chunks out of the first one. The other two only have big teeth marks in them. If your dog is not destroy all his toys these might be good.
This deal was misleading. It says that it's a "3 pack", but when it arrived there was just 1 disc. I'm rather bummed that I paid for 3 and didn't get 3. The discs are a little too heavy for distance throwing. My JRT had a few issues catching it. Otherwise descent product.
