Good trainning ball for its price. Got 500 for 150 euros with free shipping. More rounded than DHS 40+ 1 star and with better durability. Sometimes I even lightly step over some and they do not dent.
This is STIGA's training plastic ball and all I can say is don't bother. These balls come in a pack of 6 and not a single one of them was round, they all wobbled when I tried to spin them on the table. If you overlook the fact that they are not round they play like most seamed plastic balls. Reduced bounce and spin when compared to the old ball.
