This barrel is one of the best barrels I have ever tried. I've only tried 3 others, but this one is the best of them all. Balls hardly break if you use a good brand, but even with a not so good company ball, it is still accurate. I would say this barrel is pretty quiet, but it could be a little quieter. Its not thet easily seen if you get the right colors. And I think someone told me that there was a coating of teflon inside to make it more slick, but ask a pro to make sure.
The other products that I used were more consistent after ballbreak. This one basically has no accuracy after ball break you might have to squegee it twice to get everything out of it. It has holes but you can jest wash it out later.
This product is a very good choice I would advise you to buy it and even if you dont like it you can trade it in for another or even two others because it is kind of expencive. The looks are kool and so is the performance.
