this is a very good rubber, i used it on nittaku acoustic. its powerful and spinny.table tennis blades and rubbers are getting more expensive, but the butterfly products are more crazier. its too expensive. i am gonna stopping using butterfly products, cause i cant affored them. by the way, that is my opinion only: i have tried a lot of different rubber from different brand, i found out there are many rubbers are better than tenery, i think it is stupid to use tenery and dont look around for some other rubbers.
