WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

HyperX Pulsefire Haste 2 Pro 4K Wireless

What it brings

HyperX says 4 kHz wireless polling needs no extra components: the 4K receiver is in the box, and HyperX rates the battery at up to 90 hours at 1000 Hz or 30 hours at 4000 Hz with lighting off.
Manufacturer source Manufacturer source
Three connection modes (2.4 GHz, Bluetooth and a detachable USB-C cable), plus Instant Pair to OMEN gaming laptops without the receiver and NVIDIA Reflex validation for latency checks.
Manufacturer source Manufacturer source

What to check

The 4000 Hz rate applies to 2.4 GHz only: HyperX lists 125 Hz over Bluetooth and 1000 Hz wired. One onboard profile is listed, and both side buttons are on the left.
Manufacturer source
HyperX gives no switch durability rating, minimum DPI or metric cable length, and does not say whether the 61 g figure includes the cable.
Manufacturer source Manufacturer source

ASUS ROG Keris II Ace

What it brings

The Polling Rate Booster is in the box, so the 4000 Hz wireless and 8000 Hz wired rates need no extra purchase; wired USB, 2.4 GHz and Bluetooth 5.1 are all supported.
Manufacturer source Manufacturer source
ASUS publishes a 100–42,000 DPI range with track-on-glass capability, 100-million-click optical switches, PTFE feet, a 2 m paracord and five onboard profiles, and DPI, polling rate and lift-off distance can be changed on the mouse.
Manufacturer source Manufacturer source Manufacturer source

What to check

Report rates above 2K Hz need the booster attached, and ASUS rates battery life at 107 hours in 2.4 GHz mode only with lighting off (67 hours with default lighting).
Manufacturer source
