Software

Much like the Model O Wireless, the Model D- Wireless is compatible with Glorious Core. Back when doing the Model O Wireless review, I had some trouble with Core and ran into several bugs, but these have been ironed out since. I had no issue downloading and applying firmware updates, either. That said, resource usage is pretty high still.

The first tab houses the lighting settings, which are detailed below. The second tab includes button remapping. All buttons can be bound to mouse, keyboard, media, or macro functions. The third tab has performance settings. CPI adjustment ranges from 100–19,000 CPI in increments of 50 from 100–10,000 CPI and increments of 100 from 10,000–19,000 CPI, for up to six color-coded levels. Theoretically, the BAMF should support CPI adjustment in increments of 10 CPI up to the 10,000 CPI mark, but my testing strongly suggests that this functionality is not present, limiting CPI adjustment to increments of 50, as is standard for the 3370. CPI values can be entered manually on the slider. Any non-native values are automatically truncated to the next native value. Lift-off distance can be set to either 1 or 2 mm. "Debounce time" effectively controls click latency. It ranges from 0 to 16 ms and can be adjusted in increments of 2, with 10 ms being the default. Setting debounce time to 0 ms gets rid of debouncing virtually altogether, leading to eventual double-clicking. Polling rate can be set to 125, 250, 500, or 1000 Hz. Lastly, macro support and profile management are included, too. Additionally, several further settings related to wireless functionality are available. Illumination brightness can be set independently for wired and wireless modes. Furthermore, there is a setting that disables lighting after a set period of inactivity, which is the only sort of dedicated sleep mode available on the Model D- Wireless.

All setting changes 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 260 MB on average when running in the foreground, which doesn't change when minimized, be it to the taskbar or system tray. Upon exiting the application, all processes are terminated, as they should be.

Lighting

The Model D- Wireless has three physical zones for RGB lighting: the scroll wheel and two LED strips on the sides. A total of eight pre-defined lighting effects are available in the software: Glorious Mode, Seamless Breathing (RGB), Breathing, Single Color, Breathing (Single Color), Tail, Rave, and Wave. For most effects, brightness and the speed of transitions can be adjusted. Furthermore, brightness can be set independently for wired and wireless modes. This allows one to simultaneously have full RGB lighting as long as the cable is connected to the mouse, but no illumination in wireless mode to save precious battery life. Of course, the lighting can also be disabled altogether.

Color accuracy and vibrancy are excellent throughout. Below is a short demonstration video in which I go through Glorious Mode, Seamless Breathing (RGB), and Tail. Please note that illumination was set to 100% brightness:

Battery Life

Glorious states a maximum battery life of up to 71 hours without illumination. No details are provided in regard to polling rate, so I'll assume it refers to the default 1000 Hz setting. Glorious Core includes a battery charge status indicator with seemingly single-digit percentage granularity, but this isn't actually the case. Since the Model D- Wireless lacks a fuel gauge IC, these numbers are essentially made up and thus only serve as a very rough indicator. Accordingly, I can't give any estimation on battery life, as the percentage can vary wildly just between turning the mouse off and on.

In addition to the software-based battery status indicator, the scroll wheel serves as a hardware-based one in that it will light up green, yellow, or red depending on the current charge level when plugged in.

Using the included USB Type-A to Type-C charging cable, I measured the charging speed during the constant current stage, which sits at around 0.265 A. The model number of the battery is HX 582728, and it has a capacity of 450 mAh.
