Product Description

The Lofree Liquid Foundation Numpad is a compact numeric keypad designed for users who need both number input and quick calculations in one device. It suits office workers, students, or anyone who frequently uses numeric data entry and values flexible connectivity. Its tri-mode connection and calculator function add convenience beyond a standard numpad.

Key Features

Dual function as a numeric keypad and calculator, switchable with one touch, reducing the need for separate devices.
Tri-mode connectivity via Bluetooth 5.3, 2.4 GHz wireless, or wired USB-C, allowing flexible use across different setups without drivers.
Adjustable single-color warm backlight with four brightness levels, aiding visibility in low-light environments.
Full 20-key rollover prevents input conflicts, supporting fast and accurate number entry.
Calculator display supports up to ten digits, providing clear and immediate calculation feedback.

Typing Experience

The numpad uses Gateron foundation linear switches with a 40-gram actuation force, tuned for consistent and smooth keystrokes. A gasket mounting structure softens keypresses, offering a quieter and more flexible typing feel compared to rigid mounts. This makes it comfortable for extended use alongside a main keyboard.

Build Quality

The case is made of PC plastic, and keycaps combine ABS and PBT materials, balancing durability and texture. The hot-swappable switch design allows users to replace switches without soldering, enabling customization or maintenance.

Connectivity

Users can connect via wired USB-C, 2.4 GHz wireless with a receiver, or Bluetooth 5.3. This variety suits different environments, from desktop setups to mobile use. No driver installation is needed, simplifying setup across devices.

Trade-offs

The calculator function is limited to ten digits, which may be insufficient for complex calculations.
Backlight is single-color only, which limits customization for users who prefer RGB lighting.
Battery capacity is moderate at 950mAh, but actual battery life is unknown.
The compact 20-key layout may not support all specialized numpad layouts or additional macro keys.
