Verdict

The Keychron K3 Max QMK/VIA Wireless is an ultra-slim 75% layout mechanical keyboard designed for high-performance productivity and gaming, featuring a triple-mode connection with 2.4 GHz (1000 Hz polling rate), Bluetooth 5.1 (up to 3 devices), and USB-C wired options. Key characteristics include low-profile Gateron mechanical switches, hot-swappable support for easy customization, and durable double-shot PBT keycaps within a lightweight aluminum and ABS frame. Main pros include its extreme portability, full QMK/VIA programmability for custom macros, and enhanced acoustic foam for a premium sound profile; however, cons include a relatively short battery life of approximately 40 hours with RGB on (78 hours off) and the lack of shine-through keycaps, making it difficult to read legends in the dark.
