Pulsar Xlite V3 eS Review
Compared to the regular Xlite V3, the eS does several things differently. On top of 4000 Hz wireless polling, the 65 g Xlite V3 eS is also capable of 8000 Hz wired polling, and an integrated OLED screen allows for on-device configuration. In addition, the scroll wheel is made of aluminium alloy, promising improved haptics and longevity.
