The Shark Zone M20 comes in an appropriately sized box with a magnetic flap on the front, revealing the mouse inside. The back of the box on the other hand boasts key features, such as the Omron mouse switches, optical sensor and nine re-programmable buttons.
As you can see, the mouse comes with yellow LEDs, fitting in with the color scheme. There is also a nice long braided USB cable, we don't normally expect to see braided cables on budget end mice but it is a welcome addition, making it feel more premium.
There are nine buttons in total on the mouse, this figure does take in to account the DPI toggle, the mouse wheel and the main left and right clicks. Personally, I don't like re-purposing the DPI toggle, mouse wheel or the main two mouse switches, which ultimately leaves me with five extra buttons to play with- which is plenty.
The weight tuning system can be accessed via the flap towards the rear end of the mouse. There are five separate little weights inside, allowing you to adjust things to your liking. This level of customization is fantastic and isn't particularly common in peripherals at this price point.
