Retro Typewriter Mechanical Keyboard QL75 - Hot Swap RGB

In this review of the QL75 retro mechanical keyboard the bottom line is simple: this is for typists and hobbyists who want a typewriter look with modern customization. The QL75 pairs a distinctive round keycap aesthetic and ascending row profile with tri-mode connectivity, so it works wired, over 2.4GHz dongle, or Bluetooth 5.0. Its biggest selling point is the hot-swappable PCB and QMK/VIA support, which let users tailor switches, layers and lighting into a truly personalized retro board.

Key Features

• Retro typewriter design: round keycaps, a built-in device stand and a durable UV-coated finish deliver the vintage aesthetic while holding a phone or tablet securely.
• Tri-mode connectivity: wired Type-C, Bluetooth 5.0 and a 2.4GHz wireless dongle provide flexible connections for desktop and mobile setups.
• Hot-swappable PCB: the premium PCB accepts 3-pin and 5-pin switches, making it easy to change between tactile or linear switches without soldering.
• QMK/VIA programmable: full firmware support enables custom keymaps, layers and macros so the keyboard behavior fits complex workflows and gaming needs.
• RGB backlighting and metal knobs: dynamic LED effects plus multifunction knobs for volume, scrolling and device switching add useful controls and visual flair.
• Ergonomic row profile: each key row has a gradually ascending height for a comfortable, typewriter-inspired typing angle.

Who It's For

The QL75 is ideal for keyboard enthusiasts, content creators and gamers who value tactile feedback, customization and a retro aesthetic. Anyone who likes to experiment with switches, layouts or RGB effects will appreciate the hot-swap PCB and QMK/VIA compatibility.

Those who need an ultra-compact travel keyboard or require full-size number pad functionality should look elsewhere, since this is a 75% layout built around the typewriter look rather than absolute portability or full-size key coverage.
