They barely ever break in your barrel
They are a little expensive, but a little more expensive for better balls isnt bad.
I really like these balls, and At the paintball field i play at AG paintball, they use those balls there, and every time I go there, sometimes I dont break any balls, but there are sometimes where I do break just a single ball the whole day out of 2000. These are great paintballs! They are sorta hard but they dont hurt too bad, and the paint in side it shows very well (depends on what the color of it you use) (i used pink and blue with pink fill) and its not too watery or too clumpy, its just right. I rate these a 10
I recommend these paintballs because they shoot good and rarely break, but the prices arent too good but they are great balls!
