Video summary
A structured review with unboxing footage in the background and a full walkthrough of specs. The reviewer lists the numbers first: a thumb trackball with three DPI levels (1000, 1600 and 2400), 2.4G or Bluetooth connection at up to 10 metres, a 900mAh battery rated for about 90 days per charge, and an RGB ring with four effects. The box holds the mouse, the receiver, a USB-C cable and the manual, and the price is 59.99 USD with routine discounts on the brand site and on Amazon.
He maps every button - left and right click, forward and back, the ball, the light bezel, a backlight button, a DPI button, the scroll wheel, the device switch, the three connection indicators and the power switch on the base - then tests the click sound and covers the two tilt positions, flat or 20 degrees.
Pros: the anti-slip base means the mouse stays put, speed improves once you adapt, the palm fit is good, the 20-degree tilt helps the wrist, and the 2.4G receiver gave no lag. His one real complaint is that the forward and back buttons above the left click are small and hard to reach, which matters in games. He also flags the learning curve and the absence of configuration software.
