We actually ordered this ball with the ulterior motive that he will keep anyway again only a few days / hours. Now we and our Schnauzer have several weeks in use and behold the ball. No bite marks, the ball "squeaks" still (much to the delight of our dog) and we have received a response apparently processed product for little money.
Strong buy recommendation, for all dogs and dog owners who have always had to do with the life of such toys.
PS: The squeak is not too loud, so it did not really bother us when the dog makes the next room, he has been constantly bite great joy when :)
