Eweadn S9

Manufacturer: Eweadn

The Eweadn S9 is a wireless gaming mouse designed with an ambidextrous layout, making it a practical option for both left- and right-handed users. It connects via 2.4GHz wireless or USB and carries a rechargeable battery rated at 120 hours, with support for use while charging so sessions are not interrupted by a low battery. At 63 g and measuring 127 mm in length, 64 mm in width, and 40 mm in thickness, the S9 keeps a relatively compact and lightweight profile.

At the core of the Eweadn S9 is the PixArt PAW3395 sensor, which supports a DPI range spanning from 50 to 26000, adjustable to suit different sensitivity preferences. The mouse tracks at up to 650 IPS with a maximum acceleration of 50G, operating at a 1000 Hz polling rate. It offers 6 buttons in total, all programmable, including 2 side buttons and a dedicated DPI switching button, though it lacks onboard memory profiles and a profile switching button. The design omits RGB lighting, a tilting scroll wheel, and extra weights, and wireless charging is not supported.

Pros
  • The ambidextrous shape accommodates both left- and right-handed users without requiring separate versions
  • A 120-hour battery life means extended use between charges, and the mouse remains functional while plugged in
  • All 6 buttons are programmable, offering full layout customization
  • The PixArt PAW3395 sensor covers a wide DPI range from 50 to 26000, with a dedicated button for switching sensitivity on the fly
  • At 63 g, the mouse is light enough to reduce fatigue during extended sessions
  • The 1000 Hz polling rate ensures consistent and responsive cursor updates
Cons
  • No onboard memory profiles means settings cannot be stored on the mouse itself and may be lost when switching devices
  • Wireless charging is not supported, requiring a cable to recharge the battery
  • The battery is non-removable, so it cannot be swapped out if it degrades over time
  • No RGB lighting for users who prefer visual customization
  • The scroll wheel does not tilt, limiting horizontal scrolling to alternative input methods
  • There is no profile switching button, making it less convenient to cycle between different configuration sets
Who is this for?

The Eweadn S9 is well suited to gamers who prioritize lightweight, wireless performance, particularly those who switch frequently between left- and right-handed use thanks to its ambidextrous layout. The 120-hour battery life and ability to continue working while charging make it a practical choice for long, uninterrupted gaming sessions. Users who value full button customization will also find the six fully programmable buttons useful, and the wide DPI range paired with a 1000 Hz polling rate serves those who regularly adjust sensitivity to match different game genres.

Who is this NOT for?

Users who rely on onboard memory profiles to carry personalized settings across multiple devices will find this mouse limiting, as it stores no profiles on-board. Those who prefer a heavily customized desk setup with RGB lighting will also find nothing here to match that preference, since the S9 ships without any lighting effects. Additionally, power users who need a dedicated profile switching button for rapid on-the-fly configuration changes, or who require a tilting scroll wheel for horizontal scrolling in productivity or creative workflows, will find the feature set insufficient for those specific needs.
