Previously, I have been using another brand of stage 3 balls for training my kids (which I liked/found very good), but decided to give the Dunlop a try. Bought 2 packs. They are noticeably softer than the other brand, therefore slower and do no bounce as well. They are also inconsistent, i.e. some of them are softer, some harder straight out of the pack, which does not help with having consistency of bounce on the court. Overall they are ok if you want them as a junior/beginner ball, but would look elsewhere if you are looking for a better bounce/quality stage 3 ball for developing kids.
