Professional table tennis balls are convenient and very effective to have around. They are the only balls you should be using in matches and competition. Some companies may market their balls as four or five star balls to outdo others. So note a three star ball is really equivalent of a 5 star ball of another brand if they are both the brand's highest tier rated balls. Balls that are of good quality can last a long time if they are treated well. A good habit is not to leave balls on the floor, which would decrease the risk of people stepping on them.
