"It's a checklist of features in a cheap body, not a high-performance tool."
The 'Visual LED Power & DPI Display' moves information from a software driver to the mouse body. This makes it driver-free but adds a component that constantly drains the small internal battery.
This is for someone who needs a cheap, versatile-connecting travel mouse for short-term use with multiple devices like a laptop and tablet. The on-board screen and Type-C charging are conveniences that an infrequent user might value over performance.
Anyone seeking a primary daily driver for work or gaming should look elsewhere. The low DPI, questionable ergonomics for long sessions, and likely durability compromises will be a constant source of frustration for heavy users.
