Raptor M45 Detailed Features
The Corsair Raptor M45 mouse has two different surface finishes; they’re not visually obvious without a magnifying glass, but you can feel them. The top surface and primary and secondary buttons are covered with a smooth, rubberized coating, while the right and left side panels have a very fine, sandpaper-like texture for better grip.
On the bottom of the mouse we see the optical sensor and three removable metal weights. The weights comprise a metal screw and a metal donut that fits around the screw’s shaft. Corsair doesn’t give the mass of these weights but I found the difference in “feel” to be noticeable comparing the mouse with all the weights vs. none of the weights.
Note that the optical sensor is positioned near the middle of the mouse body, rather than towards the front. Some prefer a front-mounted sensor so that a twitch of the wrist can fling the cursor across the screen. Last, note that the M45 is equipped with five PTFE glide pads, rather than the three or so you’ll find on ordinary mice. The little notch by each pad makes it easy to peel off when it’s worn, and Corsair sells extra sets of glide pads for $4.95.
Right below the mouse wheel are the two DPI switches: as delivered, the upper switch increases the DPI and the lower switch decreases it. In between the switches is a three-segment red LED indicator that displays which of the three configurable DPI settings you’ve chosen. You can configure the exact value of each of these three settings in the mouse utility software. You did download and install the utility software, right?
These three LEDs serve to visually indicate which (configurable) DPI setting you’ve chosen. Pressing the button below the LEDs reduces the DPI, while pressing the button above them increases it, with the LEDs keeping track (you can, of course, redefine the behavior of these buttons.) The “Corsair” logo at the rear of the mouse is also lit, and you can turn this off if you want…but why would you want to?
These two thumb buttons are perfectly positioned. Don’t laugh: I’ve used mice where these buttons were obviously not designed for use by humans with normally-articulated thumbs.
