Software

For the Model D-, the Model D software can be used. All of the options are accessible on a single page. All buttons can be remapped, including mouse, media, and CPI functions. CPI adjustment is possible for up to six color-coded levels and a range of 400–12,000 CPI, in increments of 100. Furthermore, x and y-sensitivity is independently configurable. LOD can either be set to 2 or 3 mm. Polling rate can be set to 125 Hz, 250 Hz, 500 Hz, or 1000 Hz. Lastly, debounce time (which effectively controls click latency) can be set from 4 to 16 ms, with 10 ms being the default. Profile management and a macro editor are available as well. Upon applying any changes, all settings are saved to the on-board memory, so the software does not need to be running (or be installed) all the time. On my system, the software had a RAM footprint of 9 MB on average.

Lighting

The Model D- has three zones for RGB lighting: the scroll wheel and two side LED strips. Through the software, it is possible to select from among eight available pre-defined lighting modes. "Glorious Mode" is the default and presents a continuous color stream. "Seamless Breathing" cycles through all the colors seamlessly. "Breathing" does the same, just with transitions. "Single Color" is self-explanatory. "Breathing (Single Color)" is the same as "Breathing," just with a single color. "Tail" sends shocks of color from the top to the bottom. "Rave" engages the mouse in blinking mode. "Wave" is quite similar to "Glorious Mode," just with more blinking. Furthermore, it is possible to adjust the direction and the speed of transitions. Of course, the lighting can also be disabled altogether.

Color accuracy and vibrancy are excellent throughout. Here's a short demonstration video of the "Glorious Mode," "Seamless Breathing," and "Tail" lighting effects:
