You should contact the seller from where you've acquired the mouse from. I've checked the official website, but they don't have any peripheric products (mouse, keyboards, kits, etc). There was a user a few days ago searching for the same thing, and I believe that the Sharkk company is something no one has ever heard off. If it's possible, contact the seller and return the mouse, then buy something from A4Tech, Gigabyte, Zalman, Corsair, Razor, etc. You'll get more support instead of companies no one has ever heard of.
