Esports mouse with 3950 sensor
The BenQ U2-DW-R is a refurbished gaming mouse built around a 3950 optical sensor that supports up to 3200 dpi. Its symmetrical shape is designed for claw-grip users who favour multi-angle movement and quick lift-off adjustments. The inward-curved sides reduce thumb angle for faster index-finger clicks and balance force across the hand. Seven programmable buttons and a 24-step scroll wheel complete the control layout.
Wireless link limited to 2.4 GHz RF
Connectivity relies on a 2.4 GHz RF wireless connection paired with an enhanced receiver that reduces signal interference. The link is compatible with USB 2.0 and USB 3.0 ports for plug-and-play operation. Polling rate reaches up to 4000 Hz, but the interface remains bound to the 2.4 GHz band with no wired or Bluetooth alternatives. Buyers who need a wired fallback or a different wireless protocol will not find it here.
Upgrade from lower-polling wireless mice
This model replaces older wireless mice that operate at standard polling rates and lack the enhanced receiver. The jump is worth it when competitive play demands 4000 Hz reporting and interference-resistant 2.4 GHz stability. The claw-focused geometry and side-button placement also address comfort gaps found in ambidextrous shapes without right-side curves. Users who prefer palm grip or require more than seven buttons should look elsewhere.

Preguntas sobre este artículo
Should I choose the 3200 DPI ceiling or the 4000 Hz polling rate as my main performance target?
The sensor tops out at 3200 DPI, while the 2.4 GHz link with the 4K enhanced receiver can run at 4000 Hz polling; pick DPI for sensitivity range, polling for motion update speed.
What does the 3950 sensor designation actually deliver in-game?
It is the model name of the optical sensor used in this mouse, paired with a maximum 3200 DPI setting and 4000 Hz polling over 2.4 GHz wireless.
Does the USB 2.0 or 3.0 port limit the 4000 Hz polling in practice?
The mouse uses a 2.4 GHz RF connection with its own enhanced receiver; the USB 2.0 / 3.0 plug-and-play interface simply powers the dongle and does not cap the polling rate.
