Inward-curved design on both sides for agility and stability during mouse lift.
Bottom outline comparison
The left-side curved design, combined with the overall curve of the back,
reduces the thumb angle, which supports a faster index finger click speed.
Index finger movement is related to thumb angle.
The right-side curved design facilitates easy placement of the ring finger, which promotes balanced
force exertion on both sides of the hand and allows for better stability during mouse movement.
Others
Others without right-side curve
Others' right-side design causes
imbalanced hand force exertion.
U2-DW
U2-DW with right-side curve
U2-DW 's right-side design supports more
balanced hand force exertion.
Through experiments with different shapes and positions, U2's side button design facilitates easier thumb access.
Others
Larger angle of the thumb placement.
U2-DW
Back side button has a more forward press point, reducing the angle for thumb placement.
The enhanced receiver offers improved stability of the wireless signal and minimizes frame drops and
stuttering stemming from wireless interference during gaming.
Others
The reception footprint of other receivers has no directionality making it difficult to determine the exact direction for optimum signal reception thus resulting in weaker signal transmission.
U2-DW
The exclusive directional enhanced receiver increases the reception footprint toward the mouse which improves signal reception. A reduced range of reception at the back of the receiver can effectively minimize interference from signals originating in the rear.
The enhanced receiver doubles as a charging dock, preventing accidental cable disconnections during wired charging.
