The Lofree Flow Lite84 Low Profile is a compact 75% mechanical keyboard designed for users seeking a low-profile typing experience with versatile connectivity. It suits office workers or casual typists who want a comfortable wrist position, quieter keys, and the option to switch between wired and wireless modes. Its moderate size balances functionality and desk space savings.
The keyboard uses a skin-friendly ABS plastic case instead of metal, which keeps weight moderate and provides a smooth surface. Keycaps combine durable PBT with transparent PC legends for backlighting. The gasket mount reduces vibration and echo, contributing to quieter typing.
Equipped with Lofree’s Specter low-profile linear switches, the keyboard offers a light, smooth keypress. The 40gf actuation force helps minimize finger strain. The gasket mount and upgraded sound-dampening layers reduce noise and harsh feedback, making it suitable for quieter environments.
Users can connect via wired USB-C, Bluetooth, or 2.4GHz wireless, supporting up to three devices with seamless switching. Compatible with Windows, macOS, Android, iOS, and iPadOS. The included software for key remapping and macros works on Windows only.
