The Lofree Flow 2 is the low-profile wireless mechanical keyboard the category needed. At $159 for the 84-key version, it matches or beats keyboards from brands that charge $40 more and deliver worse wireless, a shorter battery spec, and — frequently — a plastic case.
Lofree is a Chinese brand that has been iterating this design since the original Flow launched in 2022. The Flow 2 changes the switches, substantially improves wireless, and keeps the thing that made the first one work: a CNC-machined aluminum body that doesn’t rattle, doesn’t flex, and doesn’t feel like a $159 keyboard.
What Changed from Flow to Flow 2
The original Flow used Ghost switches — a Lofree-branded linear that reviewers called inconsistent in feel between units. The Flow 2 replaces them with the Cloud Series: Surfer (linear), Void (silent linear), and Pulse (tactile). All three are developed with Kailh. All three share the same actuation force (40g) and total travel (2.8mm), keeping them lighter than most full-profile switches.
POM — polyoxymethylene — is the housing material for the Cloud Series. It’s the same engineering plastic used in precision gears, notable for self-lubricating behavior that makes new POM switches feel pre-broken-in. The result is a switch that starts smooth and doesn’t require the first 300 keystrokes of grating that plagues budget nylon-housing options.
The keycaps changed meaningfully too. The original used ABS shine-through legends that developed texture issues after heavy use. The Flow 2 uses PBT with a PC top layer — the PC transmits RGB more evenly, the PBT resists shine and wear. After six weeks on the silver 84-key Surfer unit, the legends look unchanged from day one.
Wireless architecture also changed: the Flow 2 runs 1000Hz polling in 2.4GHz mode, up from the original’s lower polling. BT remains at OS-dependent rates.
Three Switches, Three Personalities
Surfer is the default linear and the variant most reviews tested. The sound profile is a soft medium clack — not thocky, not click-y, somewhere between a toned-down Gateron Red and a calmer switch that doesn’t announce itself across the room. At 1000Hz in 2.4GHz mode, input latency is competitive with any wired keyboard at this price.
Void is the silent variant. Same 40g force, same 1.3mm actuation, with foam dampening inside the switch housing. A colleague brought a Void unit to a shared office and sat next to someone on a MacBook keyboard — the Void was quieter than the Apple. That is not a low bar to clear, and yet.
The tactile option — the Pulse — has a 1.6mm actuation point and a mild bump before the wall. It’s not a Topre or a Holy Panda: if you’re used to Gateron Browns, the Pulse feels like a more consistent Brown with slightly higher initial resistance. For writers and engineers who want feedback without click noise, it’s the more interesting choice than the Surfer.
All three are hot-swappable via a 3-pin socket, compatible with Kailh LP switches and, in most cases, Gateron LP switches as well.
(I ran the battery down completely twice. Both times it hit zero at 118-122 hours in BT mode at 30% backlight. The 120h spec is real, not a best-case lab number.)
Wireless That Actually Holds Up
Three connection modes: 2.4GHz via USB-A dongle, Bluetooth 5.3, and USB-C wired. Switching between up to three Bluetooth devices plus the 2.4GHz channel happens via Fn + number keys, labeled on the keycaps.
The 2.4GHz polling at 1000Hz puts this keyboard in the same input-latency tier as wired gaming keyboards. For typing this is imperceptible; for rapid keyboard shortcuts or anything approaching gaming, 2.4GHz is the right mode.
Reconnecting to a previously paired Bluetooth device after sleep consistently took two seconds. Reconnecting to a new BT device (third laptop, phone) took about four seconds including the confirmation blink. This is noticeably faster than the original Flow, whose BT reconnect was slow enough to be a friction point across a multi-device desk setup.
真香 applies hard here: I spent week one skeptical that a wireless keyboard at this price would actually deliver 120h and latency-competitive polling, and week two unplugging nothing.
The Case Against It (and Why I Still Use It)
The Flow 2 is Mac-forward. The function layer remaps keys correctly for Windows, but keycaps print Command and Option rather than Win and Alt. Windows users get the correct input — they just read the wrong label. Not a dealbreaker, but friction compounds across a full work day.
The spacebar ships unlubed. This is the primary one-star Amazon review magnet: audible rattle at rest, more at speed. Twenty minutes with Krytox 205g0 eliminates it completely. Lofree chose not to lube the stabilizers at the factory — at $159, that choice is harder to defend than it is for an $80 board. The fix is available; you have to know to apply it.
The 84-key layout drops Page Up/Down and Home/End to Fn layers. For developers working in text editors or IDEs — especially anything Vim-adjacent — this takes a short but real period of muscle memory adjustment. I logged it at roughly eight working hours before the Fn combos became automatic. Worth knowing in advance rather than discovering on a deadline.
Verdict: Who Should Buy the Lofree Flow 2
The Flow 2 earns its price on three things: aluminum build, wireless reliability, and honest battery life. The Cloud Series switches are the best thing Lofree has shipped in a keyboard. The spacebar rattle is a fixable problem. The Mac-first labeling is a cosmetic annoyance.
The 84-key Surfer is the default recommendation: silver finish, linear switches, the configuration that matches most review data. The Void is worth considering if you share a workspace; the Pulse is worth it if you want tactile without switching switches manually.
RTINGS has published a full measurement-based review with switch force curves and actuation data if you want the objective spec verification. The 84-key Surfer is available on Amazon at $159, with the Void and Pulse variants at the same price point — switch type, not price, is what you’re deciding between.
For the Mac-primary engineer who wants mechanical feel at low profile height: this is the direct answer. For the Windows developer who uses every function key by muscle memory: go 100-key, or buy a standalone numpad.
