The Pulsefire Haste 2 features a HyperX-branded 26K sensor in both configurations, which combines with a maximum DPI of 3200 and a polling rate of 1000 Hz for the wireless version and 8000 Hz for the wired version, resulting in pixel-perfect precision of mouse movements on-screen. For the wireless version, the battery lasts upwards of 100 hours on a single charge.
One notable aspect of these two mice is the weight. The wired version weighs 52g, as it does not include an onboard battery. However, even with the battery added to the wireless version, the mouse weighs only 60g, equalling only eight grams added for a 100-hour battery life.
