Query: Great little disc

I am not sure why the other reviewers experience is what it is, but I love these discs. I bought several of them for my Aussies. They fly far and straight. I managed to get them to hover, but the discs will eventually wear out with heavy use and then the flight characteristics do start to fail, which is why I purchased several at a time. 6 will last me a year of moderate daily use. They last on average of about 1-2 months each, with moderate daily use, before I replace them. Don't let your dog use them as a chew toy either or they won't last a day... They also float which is great around water. This is one a a few discs that my dogs aren't afraid of. I used a hard disc on my first dog and they became scared of them, so I switched to soft discs...
