Title: Good, but Dunlop is better
Review: I bought these balls to start Tennis with my 4 year old. I already had one Dunlop SpeedBall. The Gamma balls look exactly like the Dunlop ball, so at first thought the same company manufactures them. But on direct comparison the Dunlop ball is noticeably firmer in the core and has a higher bounce. I can still use these balls, but next time around I'll buy all Dunlops.
