Software

You can download the driver software from the company's official website.

It's a self-explanatory, intuitive program, but there are some strange translations here and there. On the main screen, you can import and export profiles with the Save and Load buttons, and restore all default setting by pressing Reset. The Customize page contains the button-mapping options, and you can choose from up to five different key-map profiles. You can access the macros from both here and the main window—as far as I could tell, there is no limit to how many macros you can create. The DPI Settings tab contains all the performance options; you can set the resolution, polling rate, angle snapping, and LOD here. There's also a bar for acceleration, which I would highly advise leaving on default. The Color design tab has all the lighting options you can read up on in the Lighting section.

The program consumes around 3 MB of memory while running in the background and takes up about 36 MB of disk space in my configuration—it can be considered very lightweight, which is great. Once you set everything up, you can simply uninstall the software if you'd like because the mouse has on-board memory all settings are saved to.

Lighting

The ME2 has some pretty nice RGB features. The rear Dark Project logo and transparent stripe below it light up according to the user's settings. The scroll wheel also has a lighting zone, which is linked to the set CPI level. There are a number of available options, including solid lighting, wave, color cycle, and multiple breathing effects.

I also made a video in order to demonstrate these lighting effects (as you can see, the mouse collects fingerprints really well unfortunately):
