Lofree Flow vs NuPhy Air75 V2: which low-profile board?

It depends
The short answerThe Flow wins on typing feel and sound; its full-POM switches are the best-feeling low profiles made. The Air75 V2 wins on features: 2.4 GHz wireless, VIA remapping, hot-swap with a real switch ecosystem, better battery. Feel versus function is genuinely the whole choice.

Flow strengths

  • Kailh full-POM switches: uniquely smooth, with the famous marbly sound
  • Aluminum case at a fair price, minimal aesthetic
  • Gasket mount rare in low-profile boards

Air75 V2 strengths

  • Tri-mode wireless including low-latency 2.4 GHz (the Flow's early versions were Bluetooth-focused, a real gap for gaming)
  • VIA support for painless remapping
  • Hot-swap within Gateron LP 2.0, which has many switch options versus the Flow's few
  • Mac-first keycap support in the box

Recommendation

Writers and typists who tried the Flow rarely go back; it is the low-profile board people keep. Gamers, tinkerers and multi-device users get more from the Air75 V2. If sound clips sold you on low-profile boards, those clips were probably a Flow.

Version history changes this comparison

Both boards have evolved, and older reviews describe products that partly no longer exist. The Air75 V2 exists largely because of complaints about the original Air75; the V2 generation brought VIA remapping and the Gateron LP 2.0 socket ecosystem, so a used original Air75 is a meaningfully weaker board wearing a similar name. The Flow has likewise shipped in multiple runs, with connectivity improving over time. The practical advice: match any review you read to the revision it actually tested, and confirm the current spec sheet for whichever run is in stock. Both makers iterate quietly, which mostly benefits buyers but punishes assumptions.

What owners say after six months

The long-term reports sort cleanly. Flow owners talk about the board the way people talk about a favorite pen: the POM switch smoothness does not wear off, and many describe retiring larger, more expensive boards because they stopped reaching for them. The recurring Flow complaints are ecosystem ones: fewer switch options, fewer keycap options, and wireless behavior that trailed rivals in early runs. Air75 V2 owners praise it as the board with no missing feature, and report tinkering with LP switch swaps the way MX owners do, though few call its typing feel special. In short: the Flow earns affection, the Air75 V2 earns trust.

A four-question decision path

  • Do you game wirelessly? Yes: Air75 V2, its dongle mode settles it
  • Do you remap heavily or want per-key customization? Yes: Air75 V2, VIA is the tool for that
  • Did sound tests bring you to low-profile boards in the first place? Yes: Flow, it is the board those clips came from
  • None of the above strongly? Default to the Flow for typing feel; it is the choice people regret least when the features tie

People also ask

Is the Lofree Flow hot-swappable?

It supports swapping within Kailh's low-profile format, but the compatible lineup is small, a handful of options versus the broad Gateron LP 2.0 ecosystem on the Air75 V2. Production runs have also varied over time, so confirm the current listing for your version before buying with swaps in mind.

Can the NuPhy Air75 V2 use normal MX switches?

No. It is a low-profile board built around Gateron's low-profile 2.0 sockets, and standard-height MX switches do not fit any low-profile board. Swaps stay within the Gateron LP 2.0 family, which is the largest low-profile switch ecosystem going.

Which is better for Mac users?

Both work well on Mac. The Air75 V2 ships Mac-first keycaps in the box, and the Flow also supports Mac layouts cleanly; neither requires workarounds. This is not the deciding factor between them.

Is the Lofree Flow okay for gaming?

Wired, yes, it performs like any keyboard. The catch is wireless: early Flow versions leaned on Bluetooth, which adds latency that fast-paced games expose. If you game wirelessly, verify the exact connectivity of the version you are buying, or default to the Air75 V2's 2.4 GHz dongle.
