McDermott Training Ball Carom Billiard Pool Cue Balls Professional Billiard Accessories

This thing is pretty neat ... it's very simple and obvious once you see it, and use it, but it definitely gave me a whole new perspective on how and where I was aiming.

Works great!

Should have split the cost with someone else and go the copy land to make copy of this piece of paper

This is nice and has helped me a lot. However, I wish they gave us more cardboard papers of both types of trainers. There is only 1 of each.On one, you put the ball on top of the hole, and put the arrow at the pocket.On the other, you slide the cardboard under the ball, pointing the arrow at the pocket.Both work well, but been so cool if they gave us many of each type instead of only one of each type. Wouldn't have cost them much to do this. I'm still given it 5 stars as its only suppose to come with one of each type, but still is disappointing they didn't include many more. Just my humble opinion.

Product works great. But instructions are not clear at all on how to use the product.
