Ergonomic Vertical Gaming Mouse

The eForChina JSY-03 is a wireless vertical mouse built for users who want a relaxed hand posture during long sessions. Its hemisphere shape supports the palm while a dedicated thumb groove reduces wrist and fingertip pressure. Six programmable buttons and three selectable DPI steps cover everyday productivity and casual gaming needs. The blue frosted finish on the primary buttons adds a tactile surface for grip.

2.4 GHz Wireless Limits

The mouse connects through a mini USB receiver operating at 2.4 GHz with a stated working range of up to 10 metres. Plug-and-play setup requires no driver installation on most systems. The optical sensor tops out at 1600 DPI across three fixed steps of 800, 1200 and 1600, so users needing higher sensitivity or on-the-fly adjustment beyond these presets will find the range restrictive. A wired connection is not supported.

Build Quality and Daily Use

The shell uses ABS plastic and weighs approximately 130 grams with the integrated 500 mAh lithium cell. Charging via the micro port takes around three hours for a full cycle. The compact receiver stores inside the body when travelling. Dimensions of 10.6 by 7.3 by 6 centimetres suit medium to large hands, but smaller hands may struggle to reach all six buttons comfortably. The scroll wheel uses a touch-style action rather than a traditional notched wheel.

Questions about this item

How do I choose between the three DPI settings 800, 1200 and 1600?

Press the DPI button to cycle through 800, 1200 and 1600; lower values give finer control for sniping, higher values move the pointer further per hand movement.

What does the 1600 DPI figure mean when I am actually using the mouse?

At 1600 DPI the sensor counts 1600 steps per inch of physical travel, so the cursor moves faster across the screen than at 800 or 1200 DPI.

What does the 2.4 GHz wireless interface cap in practice?

The 2.4 GHz link works up to 10 m with the included mini USB receiver and requires no driver installation.
