About product longevity: References to durability, long-lasting performance, or similar terms on this page describe the engineered properties of the string (co-polyester construction, tension retention, resistance to notching) and are not a commercial guarantee of any specific playing time, number of sessions, or service life. Tennis string longevity is inherently variable and depends on the player's style, swing speed, string tension, string pattern, racquet, frequency of play, and environmental conditions. A high-level competitive player may break a string within a single session, while a recreational player using the same string may play for many hours. TRU PRO does not guarantee any specific duration of use.

Your EU legal guarantee of conformity applies independently of the above and is set out in the official notice [above / below / on this page]. It covers defects in the product itself — such as a manufacturing fault causing the string to fail abnormally early — and entitles you to a free remedy within 2 years of delivery under EU consumer law.
