Razer is a long time prolific maker of peripherals for both the professional and casual gamer and they have now updated their flagship mouse - the Mamba (2012). Razer has the best packaging designs and have brought it to another level altogether in the Mamba. The soft rubberized texture is smooth to the touch, but may display grease stains if you like to play and eat at the same time. Rubber grips on the Mamba's right and left sides provide additional traction for your pinky and thumb. Razer has added no buttons.

8.Battery Life: Approx 16 hrs (continuous gaming)
You will want to have your mouse plugged in when you run the application and Starting the mouse-configuration program and saving changed settings are slow processes compared with using the apps that come with other mice like the M8000X and the SteelSeries Xai ($89.99 direct, 3.5 stars). In Assign Buttons, you can designate program actions for all the mouse's buttons and the motion of its scroll wheel. Manage Profiles lets you see a summary of each profile, but the cool bit is that you can assign an application to a profile and program it to automatically switch to a certain profile when you launch that application. To measure polling rate fluctuation at 1,000Hz we used a program called Mouse Rate Checker. In wireless mode it couldn't quite hold the 1,000Hz consistently.
