Which in turn solves the problems commonly found on single plane manifolds, particularly small and big block Fords.

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.

Good toy, just not their favorite
Theme: Pack of 1, Size: Ball - Large
My boys like this ball and will play with it, but it’s not their go-to favorite. It seems well made and holds up well, but they still reach for their other toys first. That said, it’s a solid addition to the toy rotation and great for mixing things up during playtime.

Good product
Theme: Pack of 1, Size: Ball - Large
This ball lasted 15 minutes with my dog before she had it in pieces. My dog is an aggressive chewer and I was hopeful but it didn't work out.

Passes excessive chewer test
Theme: Pack of 1, Size: Ball - X-Large
8 month old English Bulldog worthy. This is Blossom's favorite ball and chew toy. She has spent many hours chomping on this and it has held up very well. Occasionally she shares it with her 4 year old sister, also an English Bulldog. Highly recommend...

Best Ball Ever
Theme: Pack of 1, Size: Ball - Large, Theme: Pack of 1, Size: Ball - Large
This ball makes fetch obsessed Zeus want to play fetch 24 hours a day instead of his usual 22. Perfect size and the mesh design lets him breathe. Plus it floats. Highly recommended.
