Excerpt: I used this mouse for about a year until my hand finally gave out. More specifically, the mouse buttons take more effort than they should to press and my index finger developed a mild tendonitis.
Great mouse but has a limited lifespan. Unacceptable at price

Summary: Lots of good thigns to say about this as a mouse but after daily use over 2.5 years, the left button is now double-clicking. This is a widespread problem and requires ripping the mouse apart to repair. For a mouse that is very much at the top end of the price range, this is pretty poor.
Summary: I bought this mouse again, as my old one was left behind when I was abroad. This time however it simply does not work as it should, or used too. It is impossible to install the Razer Synapse 2.0 software, it crashes everytime I try. It does however install its own drivers to make it operate.
Summary: After installing the drivers in osx I began having issues with the mouse powering off after a few minutes of COD4. I updated the firmware and now it will only register for 10 seconds before becoming completely unresponsive.
Summary: (System: Windows 7, 64 bit new computer) No driver CD with mouse. Per instruction manual, driver to be downloaded from Razer's website. Downloaded driver, created a system restore point and installed. System reboot required. Rebooted and Windows crashed.
