Tretorn MICRO X is the ball of the future, it is the third generation of tennis balls. They were classified and approved by ITF as "Micro cell pressure". These balls are not comparable with non-pressurized balls. Each ball is filled with 700,000,000 microcells, each has a diameter of 5-100 microns. Each of these cells is filled with air. These cells work nearly as well as the pressurized air in the ball, the only difference is that the air leak.

Of course, the game features of both balls are not the same. It is very difficult to compare the pressurized with the ball MICRO X, because they are two different types of balls and because of the pressure it changes its properties very often and quickly.
