Double shell DoubleShell DS84i

The Double Shell DoubleShell DS84i is a low-profile mechanical keyboard suited for users who want a compact layout with versatile connectivity and a typing experience inspired by the Apple Magic keyboard. It fits well for office workers or casual users who prefer a slim design with tactile or linear switch options and value wireless flexibility. It also appeals to those who want easy switch customization without soldering.

Key Features

• Hot-swappable low-profile Gateron switches allow easy customization between tactile Brown or linear Red switches without tools.
• Three connectivity modes include Bluetooth 5.0, 2.4GHz wireless, and wired USB-C, offering flexibility for different devices and use cases.
• RGB backlighting with multiple effects enables visual customization, while an indicator light strip shows active settings clearly.
• A multi-function metallic knob controls volume or screen brightness, reducing the need for separate controls.
• Up to 20 weeks of battery life supports long wireless use without frequent charging.

Typing Experience

The ladder-shaped PBT keycaps elevate the center of each key, providing a smoother and more comfortable typing surface with less finger fatigue. The low-profile mechanical switches deliver a typing feel closer to laptop keyboards but with mechanical feedback. Full-key rollover prevents missed inputs during fast typing.

Build Quality

The keyboard features a rounded top design inspired by the Apple Magic keyboard, with a finely textured metallic knob adding tactile control. The case uses quality materials for a solid but lightweight build, weighing under 800 grams, making it portable without sacrificing stability.

Connectivity

Users can switch seamlessly between wired USB-C, Bluetooth 5.0, and 2.4GHz wireless modes. This flexibility suits multi-device setups and reduces cable clutter. The keyboard stores the 2.4GHz receiver in a dedicated slot for convenience.

Trade-offs

• The low-profile layout and keycap shape may feel unfamiliar to users accustomed to standard keycaps or taller switches.
• While the keyboard supports hot-swapping, it only fits low-profile 3 or 5-pin switches, limiting switch variety compared to full-height options.
• Unknown firmware update support or advanced remapping beyond macro programming may limit customization for power users.
