Ball will loose air fairly quickly
The ball seems to be made well with good supporting straps and good tow ropes. The ball performs well when towing. The problem is the ball looses air fairly quickly. At this point not sure where the air is escaping.

With no ski tow bar, hooked to my pontoons, this ball worked awesome. Keeps rope out of water for less drag!

Works Great!
I bought the booster ball to keep the tow rope out of the water and to prevent the tube from submarining on start-up. It worked perfectly.

Nice add-on for tubing
My kids begged for this. They were always getting splashed and the rope would always slow the tube when turning. With this they don't get much splash and you can really whip the tube in the turns. The rope remains out of the water and this just bounces along.
