Since the supplied rubber caps have ever worn the Razer Sabertooth, I have been looking for alternatives. Property me therefore brought in the green variant on Ebay these caps. They fit perfectly on the thumb sticks of Sabertooth - oddly even significantly better than those supplied - they have less play on the sticks and they are enclosing, so it is unlikely that they are withdrawing accidentally. They also do not seem to dissolve, as the Razer Caps. The Grip is given by the rubber pads on the edges, which works quite well, although the material is slippery. The color fits quite well, though not perfect. I am very pleasantly surprised by the things - I even have the feeling a little bit more control.
