I've used this product before, and just purchased some again. While the sleeve does add weight, it is an effective way to build up a racquet grip by one size. I have a heat gun, so the installation was quick and easy, though trimming took a bit more effort. Good product.
Works as advertised. Took me less than a minute to increase my grip size.
Easy to use , a regular hair dryer worked fine , built up 2 thicknesses and it feels like the regular grip.
i needed to increase the grip size and came across this item. very easy to use. im happy w the final result.
