Comments about Gamma 60 Pack Pressureless Tennis Balls (Yellow/Orange):
I am a 4.5 player and these balls are excellent to train with. The multi-color really helps to see the spin you put on your shots. These balls normally last one or two seasons on my Lobster machine. I normally replace once they get dirty, not because they lose their bounce.
Was this a gift?:
Bottom Line Yes, I would recommend this to a friend
