PutterWheel Golf Ball Putting Training Aid (2 Pack) Provides Instant Feedback On The Contact, Alignment & Quality Of Your Putting Stroke - Practice Putting & Improve Your Game Includes Alignment Tool

Great way to practice putting. Helps to get the ball on line and rolling true.

Very difficult to hit off line, not much of a training aid at all. Really the only way to get the rings to roll badly is by exaggerating an oblique face angle; path really doesn’t have an effect on the product unless it’s laughably off. Back to a D cell battery….

Good putting aid to show you hit the square. Helps with them pulls and pushes. Easily let’s you know when you miss hit.

Like the concept of focusing to hit the middle core of the golf ball every time but it is not easy to use because it keeps falling and if you don't set it up perfectly it will not roll in the correct line coz it wobbles. You can easy to achieve what this product trying to teach you by just drawing two lines on your golf practice ball and focus hitting the middle of it.

Improved my putting technique immensely. 5/5 recommend!
