Decent number of balls for the price! Unfortunately, my dog obliterated half of the tennis balls within an hour, but I'm sure part of that is because he likes to carry more than one ball at a time and chew on them a little before dropping for someone to throw. Otherwise, they are super bright, making them easy to see in the dark or dark places. They have some bounce to them, which makes playing fetch a little more exciting. My dog loves balls, so he has no complaints other than they don't squeak.
