Sanwa Supply Unveils Three Vertical Ergonomic Mice
Sanwa Supply has introduced a lineup of three wireless mice featuring a vertical grip design to reduce wrist strain.
Sanwa Supply has announced three new models of wireless mice with a vertical (ergonomic) grip. These devices are designed to minimize wrist strain by allowing the hand to remain in a more natural position during use.
The new mice feature a unique shape reminiscent of a joystick handle. This design allows for a vertical grip, preventing the wrist from twisting. The lineup includes three versions: the MA-EBBS537BK supports Bluetooth only, the MA-EWBS537BK operates via 2.4 GHz wireless, and the MA-EWBBS537BK offers dual connectivity, supporting both Bluetooth and 2.4 GHz.

Despite the unconventional shape, the mice are fully functional. They include standard left and right buttons, a scroll wheel, and side buttons for forward and back navigation. All buttons are equipped with silent switches, and users can remap button functions using dedicated software.

Technical Specifications and Pricing
The devices utilize an optical sensor (Blue LED) with adjustable DPI settings: 1200, 2400, 3200, and 4000. Charging is handled via a USB Type-C port. Each unit measures approximately 76×123×95 mm and weighs about 107 g.

MA-EBBS537BK (Bluetooth): ¥8,250, up to 185 hours of operation.
MA-EWBS537BK (2.4 GHz): ¥8,250, up to 267 hours of operation.
MA-EWBBS537BK (Bluetooth + 2.4 GHz): ¥8,690, up to 131 hours of operation.
