Will not buy again
Size: 80P, Color: colored
We received the balls 5 days ago and so far our dog has destroyed a ball per day. At this rate, all the balls will be destroyed in 80 days. Not a good value for this product. We have other brand tennis balls that our dog has chewed on for months that have held up. We will not buy again.

good for light chewers
Size: 16P, Color: yellow
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.
