The loss of its eye-grabbing polished shell and multi-colored LEDs has not diminished the performance characteristics of this mouse in any way. Only those who travel regularly from computer to computer will miss the dedicated 32-bit ARM processor that allowed the original Sensei to retain all of its settings between PCs. Instead, mouse settings have been relegated to a 16-bit MCU. Japanese omron switches, an optical sensor, and genuine UPE Teflon feet still give the Sensei [RAW] great presence in any OS, program, or battlespace. For those who want specifics, the Sensei [RAW] boasts an Avago ADNS-A9500 optical sensor, identical to the original Sensei, along with Omron D2FC-F-7N switches on the primary buttons, and comparatively cheaper TTC switches for the side buttons. The 16-bit MCU is actually a MC9S08JM16 Freescale 8-bit microcontroller that uses a 'true 16-bit data path' according to SteelSeries. This is denoted by the 'JM16.' UPE teflon covers 16% of the bottom of the mouse. This all boils down to the Sensei [RAW] being able to track at up to 150 inches per second and 5670 counts per inch with 30G of acceleration. It's a quick little rodent!
While the Sensei [RAW] doesn't externally flaunt its abilities as much as its predecessor, the mouse can still be personalized to the max where it counts. An unlimited number of user profiles can be created, each with its own grouping of LED brightness, CPI sensitivity, FPS rate, and macro assignment settings. The ease of navigation and simplicity of the graphic interface on the SteelSeries Engine makes accessing, modifying, and applying these advanced options as easy as a few clicks. Users can also track their button usage within matches to get a better idea of how to setup their macros more efficiently. More information on the SteelSeries Engine and additional screenshots can be found in our review of the original SteelSeries Sensei.
