Ergonomic Vertical Design

The allentian JSY-03 is a wireless vertical mouse shaped to fit the palm and reduce pressure on the wrist and fingertips. A thumb groove with an electroplated surface adds comfort during extended use. Left and right buttons feature a high-pressure blue frosted oil-spray texture for a pleasant tactile feel. It suits office workers and general users who prefer a more natural hand posture.

Simple Wireless Setup

A mini USB receiver provides plug-and-play connectivity on a 2.4 GHz link with up to 10 m operating distance. No driver installation is required on most systems. The built-in 500 mAh lithium battery charges via the supplied USB data cable and reaches full capacity in about 3 hours. If the receiver is misplaced the mouse cannot pair with a replacement unit.

Compatibility Check

Verify that your computer has a free USB-A port for the receiver. The mouse weighs about 130 g and measures 10.6 x 7.3 x 6 cm, so confirm that your workspace can accommodate its vertical footprint. Three adjustable DPI steps — 800, 1200 and 1600 — are selectable via a dedicated button. Buyers who need programmable macros or a left-handed version should consider other models.

Questions about this item

How can I confirm the 1600 DPI setting is active after pairing the 2.4 GHz receiver?

Press the DPI button to cycle through 800, 1200 and 1600 DPI; the pointer speed will change noticeably at each step, confirming the sensor is responding.

What comes in the box and is a separate charger needed for the 500 mAh battery?

The package includes the mouse, a USB receiver and a USB data cable; the built-in lithium cell charges through the cable, so no extra charger is required.

Which of the three DPI levels should I pick for general office work with this vertical mouse?

Start at 1200 DPI for a balance of speed and precision; drop to 800 DPI for detailed tasks or raise to 1600 DPI if you prefer faster cursor movement across large screens.
