The right-handed ergonomic Model D 2 Pro 4K/8KHz Edition is the director successor to the Model D Wireless. Unlike the latter, the D2 Pro does without RGB lighting and holes to achieve a weight of just 62 g. The latest BAMF 2.0 sensor along with optical switches for the main buttons are used, and up to 8000 Hz polling in wired mode or 4000 Hz in wireless mode are possible, with up to 80 hours of battery life.
