The Impact Ball is perfect for providing instant feel for correct hand position; one of the BEST products out there! I love a training aid that provides feel, allowing the golfer to feel what the perfect swing is, and what the pros feel every shot. This makes it alot easier to learn the correct swing, and groove it. I use it everyday in my training routine and recommend it to anyone who will listen. Before the Impact Ball I had difficulty with my release, flipping my hands early and losing power with every shot. Since using this product, I am hitting down on the ball, impacting it first. It is extremely satisfying seeing a divot after the ball when you are used to hitting it fat, let alone seeing the ball check inside two feet, even with a 5 iron. It gives my goosebumps...Without a doubt, my absolute favorite training tool!
