So....
This is a wee late but those mechanical switches in the Razer mice are known to fail after a few months. The good news is they are fixable! Yes you read me right. They can be fixed without buying any new parts.

Basically, these mechanical switches have a metal band that springs off the button providing a nice surgical and responsive click. The trouble is the metal. These switches come from China (not Japan, those are good for 8m+ clicks) and so the Chinese metal is a problem. The band that's intended to click becomes weak and bounces inside the switch causing two clicks for every one. The way you fix it is to remove it and bend it a little so that it's got more strength to resist bouncing. Once done reassemble and you're good to go!
