Ball was not smooth and not balanced. It did not roll true. Using this particular ball I received could actually not train you properly in good cue ball control due to over compensating for balance and true issues. Can't say if another ball would be in closer tolerances. Better to buy a real measle ball from your local table joint.

arrived on time

Great cue for training , have to reset each time you hit it, takes time but gives you immediate feedback

This is a handy little cue ball to have when learning how to play pool. I haven't yet mastered one of the recommended practice shots, but do it correctly about 10% of the time. The markings on the ball do work well to help a new player how to hit the cue ball properly. I'm happy with the purchase, and hope it helps me improve my gave over time.

This is just my experience. The ball is fine, exactly as expected. No problems and I can very much recommend this to anyone that wants a practice training cue ball. But if you are like me…I didn’t really think this through. For one thing in order to really use it, you have to set it up CORRECTLY before each shot. That’s fine. But it isn’t as easy as I had thought. You need it to be vertically 90 deg from the horizontal plane (the table) and also to be useful (unless you are only practicing where hitting it consistently) also 90 degrees from the object ball plane. This is NOT easy to do on a pool table, at least for me. It becomes ridiculous, I’m spending more time trying to get the ball correct on the table than shooting. You can use the red stripe though and that makes it easier. But in the end I feel I could have used a striped ball and saved my money.Edit to update how wrong I was:I just spent some more time using the ball, and I was wrong. Now, I only have experience with this one brand, and do expect they all are about the same in usefulness but can only speak about this one.So, it’s not that hard as I made it out to use. For myself, I needed to use “normal” chalk as the higher end doesn’t leave marks as well. Also have a micro cloth or rag handy to wipe off the ball after each shot.So far I used it to check I’m hitting dead center and low enough on straight draw. It revealed I wasn’t.Set up a striped ball (makes it easier to align) 5” from the side pocket, and the ball just near enough that I can use a longer bridge hand. Align the red stripe to be parallel with the stripe ball stripe, so you know you are hitting ball to ball center. Also, make sure to position so the “high” label is on top and low right at the bottom. Apply chalk liberally, aim as if you are playing in a tournament, and shoot.Notice how the cue and object ball react and then look closely at the ball to see where you really hit it. The only hassle for me is I have to keep putting on and taking off my reading glasses. It can be hard to see the blue chalk mark, but it’s there.This revealed I was not hitting as low as I had thought, and also consistently hitting about 1/8” to the right. I did it about five times in a row to check it was consistent. It was. Then realized I was bringing my back hand slightly in to my body when I shot. Also realized I was not letting the cue stick “hang” down like a pendulum, but instead grasping it too hard.This revelation immediately improved my shooting, on long shots, cut shots, really everything. I mean I’m not a perfect shooter but the improvement was amazing to me. All because of this ball. Or this type of ball. Not sure just a striped ball would have given me this much feedback on my hits.It also surprised me because I was always able to shoot from one end of the table and have the cue ball return right to my cue, yet this showed me that didn’t mean I was hitting dead center, maybe I was subconsciously adjusting to make it come back to the tip?It takes time and patience. I’m not going to use it every practice session, but I am going to use it more and also for other types of shots, English, also break shots where I have less control.Am going to also try and figure out the other side of the ball (opposite the one with concentric circles and labels like high, low, left, right, etc.) and what that is useful for.

My daughter, a teenager is enjoying using this to learn Billard skills and improve her game. She loves it!

Found another one just like it 5 bucks cheaper. Would have been nice to include some instruction with it as the most accurate way to use it, but nope nothing in the cute little box except the ball.

It's a good training tool to give you better visibility on what you are aiming at and where the outcome will be according to your eye sight, skill level, and experience
