Good price, but like the first reviewer, the first ball lasted about 30 seconds, until my German Shorthair made a big squeeze, and the rubber ball split around the seam. Regular tennis balls at least last a day or so.
To be fair, my dogs have eaten pretty much every toy on the market so far. These balls are no exception. They lasted approximately two minutes before they were in pieces and being swallowed. There are other more durable brands out there- go for them instead!
