Will suffice as practice balls with a ball machine. It does not feel like the real thing. If you hit with this ball often, you will have to adjust your grip and swing during match play. With this ball, you need a tight grip which is the exact opposite when playing with the regular ball.

Unless you live in high altitude, pressureless tennis balls are not ideal for match play. They are ideal, however, for tennis hoppers and ball machines. Regular tennis balls go "dead" in a matter of weeks, and constantly having to replace them is a chore. I have had the same balls for well over a year, and 50% are still "good"; while the other 50% finally had to be tossed. So, for practice or teaching, these balls are very economical in the long run.

We have a har try court and since these balls do not have a great bounce its a bit difficult. I would say good for small children as they are accustomed to much less bounce.
