The training balls of Joola are very good quality. Have been 4 Blister bought them and so far had very good experiences with it. The balls were very stressed, several times a week, for several hours, even on outdoor plates with metal nets and have hardly broken balls. They are pretty hard to jump well and take on enough spin to properly train with it can. Pro Ball 0.40 cent is now no bargain price, but if you want to buy only by 12 balls but cheap enough and the balls are then in the price / performance ratio really good!
