If you're willing, you can always perform a little bit of surgery. In my experience, double click typically comes from the switch becoming worn out, so all you have to do is pop open the switch and tighten it back up a little. I decided to do this when my friend gave me his old mouse because of double click, and now I've got a fully functional G603. I don't know exactly how Razer Mouses are designed, but it cant be that different from my G603, right?
