Loud sound, without the speed glue! F3 BigSlam generates a loud crack when you hit the ball! The distinctive sound has been firmly and permanently incorporated into Desto F3 Big Slam, but do not speed glue this rubber. This is the loudest Desto Formula rubber that Donic has ever produced. Donic Desto F3 BigSlam reproduces the loud sound that you got during the classic times of speed gluing. However, this rubber does not require speed glue and must not be speed glued! The distinctive sound has been firmly and permanently incorporated into the rubber. BigSlam is somewhat softer, but not significantly slower than its successful sibling Desto F3. It has the same amazingly simple ball control, but gives the same effect as optimum speed glue. Whether you prefer Desto F3 or Desto F3 BigSlam is a matter of taste-or, should we say, of sound preference.

Donic Desto F3 BigSlam is recommended for players who have previously used speed glue and for those who value sound and outstanding ball control qualities rather than maximum speed.
