cheaper pressureless tennis balls... how are they?

[mmaster]

so looking at cheaper alternatives to tretorn micro X balls,
i see they have penns and gammas but i haven't heard nice things about them.

i noticed they also have Unique pressureless balls. are these any good?

which are some of the better pressureless balls that are cheaper than the tretorns?

I buy a few bags of Gamma pressureless every black friday, and have been using them for years. Pretty darn good balls considering they're pressureless.

Not as bad as most people make them out to be! And they honestly last a whole lot longer as well.

Personally for recreational use I'd choose quantity over quality so I normally buy a few bags of prince pressureless trainers. It comes up to about $0.50 a ball and I think the quality is really decent.
