Used these for kids to use on a balloon launcher as alternative to water balloons they are good enough for that, can’t say how well they work playing tennis?

they squeak
Color: Multicolor
my dog loves these balls because they squeak unlike other brands.... and the 2.5 inch is a good size for a med to large dog... only issue is i go through a ball a day... because my Pit loves to squeak the life out of them.... good for about 2000 squeaks....
