    The Lofree Flow set a benchmark for the typing experience on low-profile mechanical keyboards when it first came out a few years back. However, it did have some flaws, such as limited customisation options and no way to change the typing angle. While the Lofree Flow Lite tried to fix some of these issues, our review of the Flow Lite84 pointed out that the customisation software still had several limitations, and the material durability was a concern.

    Improvements with Flow 2

    Now, Lofree appears to have tackled many of these concerns with the introduction of the Flow 2, a new high-end low-profile keyboard. The Flow 2 will sport a fully aluminum chassis, plus it retains the convenient hardware switches for connectivity and OS modes from both the original Flow and Flow Lite. Like the NuPhy Air75 V3, the Flow 2 will also feature a gasket-mounted design. Connectivity options remain varied, including wired, Bluetooth, and 2.4 GHz, similar to the Flow Lite.

    Design Changes and Features

    One of the most obvious upgrades in the Flow 2 is the redesigned keycaps and its unique asymmetrical look. Unlike the original Flow and the Flow Lite, which had a more standard design, the Flow 2 has a broader bezel on the right side. This isn’t just for aesthetics; it cleverly conceals hardware for a touch surface, which can be customised to mimic functions of the knob found on the Iqunix Magi65 Pro (currently $132.99 on Amazon), a keyboard we reviewed as well.

    The new keycap profile, another significant upgrade in the Flow 2, combines elements of the classic Cherry profile with the uniform-height keycaps seen in the Flow Lite. As is standard for most low-profile keyboards, the Flow 2’s keycaps will be of uniform height, but they will have a top sculpt similar to a Cherry profile. This design aims to provide a more familiar typing experience for users transitioning from full-height mechanical keycaps, while still keeping the lower profile. These keycaps will also be shine-through and made of POM, which should enhance durability compared to ABS, as POM is known to be more resistant to oils common in keycap materials [PDF].

    User-Friendly Design Choices

    Lofree appears to continue its strategy of appealing to MacBook and laptop users, as evidenced by the USB Type-C port located on the keyboard’s right side. This suggests that the included USB cable will again feature a right-angle connector, similar to what was provided with the Flow and Flow Lite.

    Internally, the Flow 2 boasts improved hardware and firmware, making it compatible with VIA, a popular open-source keyboard customisation platform. This allows users on Linux, macOS, and Windows to remap keys, assign macros, and modify touch bar functions.

    The Flow 2 will also come with a larger battery compared to both the Flow Lite and the original Flow, featuring a 3,000 mAh battery in the 84-key version. While exact battery life remains uncertain, it’s known that VIA-compatible keyboards can be slightly less efficient than those with proprietary firmware. However, some exceptions exist, like the Iqunix Magi65 Pro, which manages to last hundreds of hours on its 3,000 mAh battery.

    New Switches and Pricing

    As part of the Flow 2 launch, Lofree has also introduced three new full-POM switches, seemingly in collaboration with Kailh on their design. These new switches are said to have a redesigned backlight window for improved shine-through. While the Flow Lite’s backlighting was decent, the new switch design could potentially enhance battery life with backlighting turned on, as users may be able to reduce brightness while keeping similar illumination levels.

    The new switch options include the Void, which is a silent linear switch, the Pulse, a tactile switch, and the Surfer, a standard linear switch.

    Lofree has launched the Flow 2 for pre-order on its website. Interested customers can reserve a Flow 2 keyboard for just $1, which offers a significant discount. The full Kickstarter campaign will kick off on July 10, with prices eventually rising to between $189 and $209.

    The pre-launch pricing is relatively reasonable considering the premium materials and switch options. However, the final launch prices may seem quite high, especially when compared to the recently unveiled NuPhy Air75 V3 and the respected Iqunix Magi65 Pro.

  • NuPhy Air75 V3: Wireless Low-Profile Mechanical Keyboard with Long Battery Life

    NuPhy Air75 V3: Wireless Low-Profile Mechanical Keyboard with Long Battery Life

    Key Takeaways

    1. Enhanced Features: The Air75 V3 comes with long-travel Gateron LP 3.0 switches, a gasket mount, and an improved chassis for better sound quality and feel.

    2. Low-Profile Design: It features a slim profile with a front height of 13.2 mm and a total key travel of 3.5 mm, making it compact while still providing a comfortable typing experience.

    3. Customisation Options: Users can replace a knob with a key switch, offering flexibility in navigation and two height options for the knob.

    4. Software and Functionality: Utilizes NuPhy IO 2.0 for customisation and macros, simplifying firmware updates compared to other keyboards, but lacks the depth of competitors’ software.

    5. Pricing and Availability: Priced at $139.95, the Air75 V3 is competitively positioned against similar models and is available for pre-order until July 10, 2025.


    NuPhy’s new Air series low-profile mechanical keyboards made a big impression when they were first introduced. They offered a level of customisation and a premium typing experience that were usually found only in full-height mechanical keyboards, all while being more compact. However, over time, other brands like the Iqunix Magi65 Pro and Lofree Flow Lite have emerged and outperformed the Air series with their gasket mounts and the smooth Kailh low-profile mechanical switches, as noted in our earlier reviews.

    Introduction of Air75 V3

    Recently, NuPhy has officially shared all the specs of the anticipated Air75 V3, which includes the same long-travel Gateron LP 3.0 switches seen in the Kick75 Low. They’ve opted for high-quality materials, a gasket mount, and a revamped chassis design, all of which aim to enhance the sound quality and feel compared to the previous tray-mounted Air V2 series. Additionally, the Air75 V3 comes with a swappable knob, allowing users to select between a switch in the top right corner or a custom knob.

    Design Features

    The standout feature of the NuPhy Air75 V3 is its low-profile design. It boasts a claimed front height of 13.2 mm—almost 1 mm taller than the Magi65 Pro we measured—but compensates for this slight height increase with a generous 3.5 mm total key travel, courtesy of the new Gateron Low-Profile 3.0 switches.

    Customisation Options

    Another intriguing aspect of the Air75 V3 is the inclusion of a knob that can be replaced with a key switch, providing users with the choice of a full navigation column on the right side. The knob comes with two height options: a short one for portable use and a tall one for more stationary setups at a desk.

    Software and Functionality

    In contrast to keyboards such as the Iqunix Magi65 Pro and the earlier NuPhy Air series, the Air75 V3 utilizes NuPhy IO 2.0 for customisation and macros. While this software is browser-based like VIA, and offers features like macros and knob customisation, it lacks the depth of VIA or Keychron Launcher, not to mention QMK. However, NuPhy IO does have an advantage when it comes to firmware updates, as many QMK/VIA keyboards need special software utilities for flashing firmware, whereas it’s much simpler to do in NuPhy IO for the Air75 V3.

    Battery Indicator

    Furthermore, NuPhy has added a useful battery indicator LED in the Air75 V3 that provides more detailed battery percentage information than what was available before.

    Pricing and Availability

    Currently, the Air75 V3 is available exclusively on NuPhy’s website for $139.95, which is quite similar to the Iqunix Magi65 (currently $132.99 on Amazon) and $10 less than the comparable Lofree Flow84 (currently $149.99 on Amazon). Pre-orders will remain open until July 10, 2025, after which the keyboard will be available as an in-stock item.
