Really interesting little gadget. This is a beginner’s only tool and was really developed to help kids learn a straight stroke so they won’t jack up your table felt, so keep your expectations in line with it. When you look at it for what it is though, its a great little trainer to help kids work out a nice, even stroke.
Manufacturer’s Description – Take the stress out of a game of pool with the Junior Shark Guiding Wheel. This new tool is perfect for the junior player who might be a little less than careful with their pool cue. Just clip it over the tip of your pool cue and slide it down below the ferrule. The wheel will protect your pool table’s felt from unintentional rips and scratches while teaching children (or any player for that matter) a smooth and consistent stroke.
Typically sells for around five bucks.
