Great additional bumper.
We have a boat that is wider around the tower then where the cleats are. These bumpers are great for filling that gap and keeping the boat off the dock. I ordered 4 of them and still use 2 of the standard tube bumpers around the widest part and then put of the balls up front and one in back. When we tie up with other wake boats we use all 4 two on each side. The only down side is these are really just the bouncing balls with handles that kids ride. You can see where the ball is re enforced and textured to hit the ground on these. If you want these bumpers but in a different color look to toys r us or target. You can get colors or action figures on them.
