What is the String Thing? This new, innovative product will take your game to the next level. Have you ever notice players "straightening" the strings between points? Do you do this? During points as you strike the ball, the strings will "shift" out of position. This inconsistency in the string pattern can cause more miss hits. Any serious tennis player knows that straight strings mean more control, better shots, and a better game. And, now you can do it in seconds. Use String Thing between points. Use it before putting your racquet away to extend string-life. The more you use it, the straighter your strings will stay. Using the String Thing couldn't be easier. Just brace your racquet against your hip or side. Place the String Thing on the misaligned strings and press down firmly. Then, just roll up and down. That's it. No need to go side-to-side, as the String Thing adjusts cross-strings at the same time.
