## Description

The BG66UM has a 0.65mm thin gauge and the perfect balance of maximum speed, control and durability, making it the best choice for the world's top players.

Review: Strings lasted only 1 day - The strings broke just after 1 use. The racket was strung at 27lbs. Never had such poor quality with BG66 Ultimax.
Review: That is the only brand we buy to replace the string. My 14 years old was able to last 2 years with the previous one we bought.
