I only get about one match sometimes less. Tournagrip durability is not good. One reason for this might be the fact that you have to stretch it more then other grips to get it to cover the whole handle. I have changed to Yonex Super Grap it has a similar feel to tournagrip but is a little thicker resulting in better durability.
