12 " too short, no direction.
Style: Sport, Size: 12in
I got the twelve inch handle. It is too short and does not flex enough to release ball in right direction. Its almost impossible to aim and doesn't sent the ball far enough.

Not for a dog that chews
Color: Black
The color tags came off so this was a chocking hazard for my blind dog. I ended up throwing away. My dog is not a destructive chewer.

My dog’s favorite toy
Color: Black
I’ve bought my dog 1 million different dog toys. This is his absolute favorite. I would highly recommend them. The handle makes it easy for the dog to grip.
