The FL·ESPORTS OG104 is a tri-mode mechanical keyboard featuring a full 104-key layout. It supports wired, Bluetooth, and 2.4 GHz wireless connections, allowing seamless switching between Mac and PC systems. The keyboard incorporates silent switches (Brown type) that reduce audible click noise while maintaining tactile feedback. A built-in 4000mAh rechargeable battery provides extended wireless usage without frequent charging.

The keyboard uses SA profile PBT keycaps, which are known for their durability and resistance to shine over time. The keycaps are thick and double-shot molded, ensuring long-lasting legends. The housing is constructed from robust ABS plastic with a retro aesthetic that complements vintage or modern desktop setups. The hot-swappable switch sockets allow users to change switches without soldering, offering flexibility for customization.

The OG104 delivers stable performance across all three connection modes. Bluetooth pairing is straightforward, and the 2.4 GHz wireless dongle ensures low-latency response suitable for gaming. The wired USB-C connection provides a lag-free experience for competitive play. The silent switches reduce typing noise, making it suitable for shared workspaces or late-night use.

The full-size layout includes a numeric keypad, useful for productivity tasks. The 4000mAh battery capacity enables long usage intervals on a single charge. Under typical mixed usage, the keyboard can last several weeks before needing to recharge. The battery powers the RGB backlighting, which offers multiple lighting effects but can also be disabled to conserve power.

The keyboard supports NKRO (n-key rollover) for accurate simultaneous key presses, enhancing gaming reliability. The product is priced at $89.44, positioning it as an affordable option for users seeking a feature-rich mechanical keyboard. The combination of tri-mode connectivity, hot-swappable switches, SA PBT keycaps, and a large battery delivers solid value for budget-conscious gamers and typists.
