Good bounce and pretty durable
Reviews for Butterfly ABS Balls 3-Star S40+ - Pack of 12 (3)
Surprisingly great. I've hated every butterfly 40+ ball up to this one, but someone at the club had one of these, it felt good, so I tried a pack. What an improvement, it's close to the Nittaku imo. If only they'd price it better I might be tempted to switch.
Feels quite different from a normal G40+ ball, with which I used to play before but quite similar to Nittaku 3*. Most of them are round and they are quite fast although the durability is very bad. The paint wears of very quickly and is very easily broken, for example by smashing into the wall. Overall, I recommend using Nittaku balls or butterfly g40+ for now until this gets some improvement.
