Improve your focus on the ball: I have been curious about what any training paddle can do for you. I will say it helps you slow down and focus on the ball. You wont be taking blind big swings on put aways because you'll whiff. This will help you watch the ball all the way into your paddle again. Honestly you should play games with it more than drill. Side note, you should add weight to it, if you don't when you switch back to your main paddle it'll feel like you are swinging a log.
True Master of Pickle: This is my paddle of choice. Remember, it's not the size of the paddle, it's how you use it. :)
Absolutely amazing: I love this thing! I use it daily to practice indoors with a foam ball on my walls. Getting used to this device makes a real paddle amazingly easy to coordinate. The small head lets you get balls that go close to the wall, furniture, etc. without hitting them. Real carbon face allows for proper topspin action too! This was the only store ANYWHERE that had it in stock and it arrived quickly.
Great practice paddle: Great for drilling with people, the wall, or a machine. Love the construction quality and carbon fiber surface.
