Software

The OGM Pro comes with its own lightweight software. All options are accessible through several tabs. The first tab includes button remapping to mouse, keyboard, media, and macro functions for all but the left button. The second tab has CPI adjustment for up to five color-coded levels, at a range of 50 to 26,000 in increments of 50. Non-native values are truncated to native ones. The third tab houses a macro editor, while the fourth tab includes the Windows pointer settings. The fifth tab allows setting polling rate to 125, 250, 500, or 1000 Hz. "Respon" denotes debounce time, which effectively determines click latency, and can be set to 1, 2, 4, 8, 10, 20, or 32 ms. Lift-off distance can be set to 1 or 2 mm. "Ripple" enables smoothing, which decreases cursor jitter at higher CPI steps at the expense of increased motion delay. "MotionSync" synchronizes SPI reads with USB polling events and likewise increases motion delay when enabled. Lastly, a setting for angle snapping is also present. Profile management is available, too.

All setting changes are saved live 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 14 MB on average, which doesn't change when minimized to the system tray. Upon exiting the application, all processes are terminated, as they should be.

Battery Life

Waizowl states a maximum battery life of up to 70 hours using 2.4 GHz wireless. The battery life indicator within the software seemingly features single-digit precision, but is quite unreliable and inaccurate in practice. Still, after 6 hours of continuous usage, it stood at anywhere between 90-94%. Assuming linear consumption, the number given by Waizowl therefore is within the realm of possibility. In addition to the software indicator, battery level can also be checked by pressing the CPI button once.

Using the included USB Type-A to Type-C charging cable, I measured the charging speed during the constant current stage, which sits around 0.193 A when lifted and 0.174 A when not lifted. The battery has a capacity of 300 mAh and utilizes a 3-pin JST connector.
