Technical data and features

Lofree Edge

The compact low-profile keyboard has a particularly flat design, which is achieved through a lightweight housing and the use of carbon fiber and magnesium alloy. The structure appears stable, but at the same time pleasantly light, which makes the keyboard suitable for mobile use. The built-in Kailh POM Switches 2.0 further reinforce the flat profile and provide a smooth typing feel that relies on durable materials.

The keys are made of robust Dye-Sub-PBT, which enables high resistance to wear and tear. In combination with the innovative PCB gasket assembly, this results in a muted sound characteristic that supports a quiet typing experience. The keyboard is clearly designed for functionality, as it remains easy to read even in the dark thanks to its simple white backlighting.

In everyday use, the dual-mode connection of Bluetooth and USB-C proves to be flexible for different systems. The ability to pair several devices simultaneously makes the model suitable for users who frequently switch between notebook, tablet and desktop. The battery life is wide-ranging, depending on whether the backlight is activated or not, and therefore offers solid endurance for everyday use.

Lofree Flow 2 – 68

The Flow 2 model with 65 percent layout focuses on a clean design language with an anodized aluminum housing that is both elegant and durable. The newly developed POM Cloud Series switches with 40 grams of actuation force create a smooth typing feel, making the overall profile of this keyboard designed for comfort. The built-in kickstand provides additional angle flexibility, allowing you to switch between a flat stance and a much steeper 7-degree angle.

The touch bar for controlling volume and brightness adds a modern control element to the layout that is intuitive to use. The double-injected PBT PC keycaps ensure even illumination of the white backlighting and are made of durable materials. The design of the keyboard follows a gasket assembly, resulting in a softer typing action that effectively reduces vibrations.

In terms of connectivity, the model relies on three different operating modes, including 2.4 GHz wireless, Bluetooth 5.3 configuration and wired USB-C. The keyboard can be fully customized via VIA, enabling both macros and individual layouts. The integrated battery provides sufficient runtime for daily use, whether working with backlight or not.

The calculator

The compact calculator has an ergonomic housing that makes it easy to use and at the same time offers enough space for a 10-bit LCD display. The shape is designed to make even longer entries comfortable, as the device is easy to hold and can be used on the move thanks to its low weight. The display offers a clear presentation, making numbers and results easily recognizable.

The device uses mechanical Gateron Blue switches, which provide characteristic acoustic and tactile feedback. These switches support precise input and provide a classic mechanical typing feel that is distinctly different from the traditional rubber dome mechanism. The sturdy construction ensures that the keys work evenly and do not lose feedback even with frequent use.

Power is supplied by a single AAA battery, which gives the device a particularly long operating time of up to 500 hours. The economical operation makes the model a practical addition for the desk or on the move, as no regular charging is required. The combination of mechanical input, robust construction and long operating time creates a reliable tool for everyday computing tasks.

Structure and features of the Lofree Edge

The keyboard from above in combination with two different lower sections. The upper shell is visibly made of carbon fiber, while the two lower housing variants have perforated ventilation openings. The underside appears slightly angled and both bottom cases have retractable feet. The right bottom part is light gray, the middle one dark gray and gives the impression of a robust magnesium alloy.

The keyboard in side profile. On the left you can see the flattest part with a height of 5.4 millimeters, on the right the thickest part of 15 millimeters. The profile looks very slim and follows a line that rises gently towards the back.

The upper side consists of a carbon fiber top case with a 3K twill structure, while the lower case is made of a perforated magnesium alloy. Both materials are clearly separated from each other and emphasize the two-layer structure.

The PCB gasket assembly aims to create a more comfortable typing experience without making the case heavier or bulkier. With this design, the gaskets are integrated directly into the PCB, resulting in a smoother and softer typing experience. As space in the flat housing is limited, permanently soldered switches are used to ensure a stable connection between the switches and the PCB.

The cavity inside is not filled with silicone, but with specially shaped foam, which adds less weight and at the same time effectively contributes to noise reduction. This dampens the typing noise without compromising the lightweight construction. This type of construction is particularly suitable for quiet environments such as libraries or work areas where there is a need for restrained sound.

The combination of reduced mass, integrated gaskets and targeted damping creates a balanced typing feel that improves both ergonomics and acoustics. The overall result is a flat, quiet and precise keyboard that underlines the series’ claim to a high-quality typing experience suitable for everyday use.

The Full-POM-Switches 2.0 rely on a particularly flat design, which was developed on the basis of the Flow switches and, together with Kailh, enables a further reduction in height. The development focused on creating a smooth and uninterrupted keystroke without simply shortening the height of the switch housing. Instead, the entire key travel was adjusted across various prototypes and tested in several stages from an initial 2.8 millimetres down to 1.0 millimetres.

The final result is a switch with a total travel of 2.4 millimetres, which produces a smooth, linear touch and thus supports a consistent typing feel. The POM material ensures low friction, making the switches quiet and stable while offering a long service life. The construction is specially designed to provide constant feedback even at high typing frequencies.

This ultra-flat design results in a more relaxed hand position when typing, as the fingers remain more naturally curved and the wrist rests flatter. This reduces strain during long typing sessions and contributes to the ergonomic alignment of the entire keyboard series.

Bluetooth 5.3 and a wired USB-C connection are supported. The macOS, iOS, Windows and Android systems are compatible. The maximum battery life is up to 130 hours without backlighting or around 10 hours with backlighting activated, with a battery capacity of 2000 mAh and a charging time of around three hours.

The keyboard works with a very low input delay and relies on a wired USB-C connection, which enables polling rates of up to 1000 Hertz or one millisecond. This level corresponds to a significant increase compared to the usual 125 Hertz and ensures that commands are recorded with virtually no noticeable delay. Every input is registered immediately, ensuring precise and loss-free writing or gaming behavior.

Structure and features of the Lofree Flow 2 – 68 %

The surface of the Flow 2 is finished with a 205-grit anodizing process, which creates a particularly fine structure and gives the aluminium housing an even, satin-like feel. This treatment increases resistance to signs of wear, reduces fingerprints and ensures that the material is pleasantly smooth to the touch. The light refracts discreetly on the surface, creating an unobtrusively elegant impression.

Compared to highly glossy or coarsely textured coatings, this grain offers a balance between visual restraint and functional benefits. Every touch feels controlled and of high quality without the texture being too dominant. The finely tuned grain conveys a deliberately designed feeling of precision and quality.

This finish is not just for looks, but also improves the grip stability of the case in everyday use. The Flow 2 thus combines a surface structure designed for durability with a pleasant feel that consistently underlines the high-quality overall impression of the aluminum body.

The Void switch is designed as a quiet linear switch and provides a firm, controlled feedback that is particularly suitable for night-time typing, concentrated programming or collaborative working environments. The design aims for a quiet typing experience where each input is smooth and without acoustic distraction. This creates a switch profile that is both precise and unobtrusive.

The revised switch structure of the Flow 2 integrates significantly enlarged light windows, providing more than three times the surface area of the previous generation. This adaptation ensures brighter and more even illumination, so that the lettering remains clearly recognizable even in reduced lighting conditions. The lighting is evenly distributed and avoids harsh points of light or uneven shadows.

This combination of a quiet linear touch feel and optimized illumination creates a switch design that is both functional and atmospheric. The soft brightness emphasizes the character of the keyboard without dazzling and contributes to a harmonious overall effect that is suitable for both productive work and relaxed typing.

PU foam forms the top layer and is used for general noise and vibration reduction. Beneath this is a PET damping layer, which supports additional stability and a more even distribution of impact noise. The next layer is an IXPE switch pad, which softly cushions the switch base and further reduces the sound.

A silicone sandwich pad completes the construction with a flexible intermediate layer that effectively absorbs vibrations. The final layer is a gasket pad, which provides a decoupled assembly and makes the typing feel smoother and quieter. These five materials work together to create a significantly dampened, controlled acoustic experience.

The keyboard supports both a 2.4 gigahertz connection and wired operation via USB-C, achieving polling rates of up to 1000 hertz or one millisecond. This transfer rate ensures that inputs are processed without any noticeable delay and even fast processes during gaming, writing or programming are recognized precisely. The high response speed is a technically sophisticated feature that has been integrated into a compact and modern design.

In addition, the model offers a triple connection selection, consisting of USB-C cable operation, Bluetooth 5.3 radio and a stable 2.4 gigahertz radio connection via an enclosed dongle. This combination ensures that the keyboard can be used flexibly in different environments and the 2.4 gigahertz connection in particular offers a reliable alternative to Bluetooth. This makes the keyboard suitable for both mobile scenarios and stationary workstations.

The structure and features of the calculator, which would have liked to be a fully-fledged keyboard.

Even at first glance, the calculator looks like a compact keyboard, as its structure clearly goes beyond the typical range of functions of a simple calculator model. The housing consists of a sturdy construction that sits comfortably in the hand and is reminiscent of the layout of mechanical input devices thanks to its clear edges and ergonomic shape. The keycaps are individually designed and are noticeably spaced apart, which enables precise input and further emphasizes the character of a small keyboard. Above the keypad is a wide LCD display that clearly shows numbers and results and makes the upper area look like a function line.

Inside, the calculator works with mechanical Gateron Blue switches, which generate unmistakable tactile and acoustic feedback. This choice of switches is unusual for a device of this size and gives the operation the feel of a real mechanical keyboard. Each input is clearly defined and provides stability and consistent feedback. The overall design is therefore more robust and of higher quality than conventional pocket calculators and shows that the design is deliberately based on the typing feel of mechanical keyboards.

Power is supplied by a single AAA battery, which means that the device remains ready for use for a long time without recharging. The maximum runtime of up to five hundred hours shows that the calculator is designed for efficiency and works reliably in everyday situations. This gives the impression that this model wants to be much more than just a calculating tool. With its mechanical switches, clear key structure and high-quality construction, it looks like a compact input device that would prefer to appear as a fully equipped keyboard itself.

The retro design of the Digit is based on classic typewriters and consistently implements this character with circular keys. The dot-shaped keycaps are reminiscent of the mechanics of past decades and deliberately evoke a nostalgic feeling that appeals to both younger and older users. The design combines a traditional appearance with modern functionality and creates a visual bridge between earlier input devices and today’s technology.

The built-in Gateron Blue switches reinforce this impression with their clear, audible click each time they are pressed. These switches generate precise and defined feedback, which is a characteristic feature of mechanical key technology. The touch is light, yet tactile and supports an input that deliberately sets itself apart from the typical, softer membrane switches. This creates a user experience that is not only functional, but also emotionally reminiscent of earlier writing instruments.
