PickGuideNuPhy Air75 V2 Review: Is Their Most Popular Keyboard Worth It?
NuPhy built its name on low-profile mechanical keyboards, and the Air75 V2 is the one with by far the most owner reviews of anything in its current lineup. It's a 75% wireless board aimed at people who want a slim, laptop-style typing feel without giving up hot-swappable switches or open QMK/VIA firmware. Here's what you actually get for $129.95.
The Air75 V2 pairs Gateron low-profile mechanical switches (hot-swappable, so you can pull them without soldering) with an aluminum top frame and an ABS plastic bottom case. It connects three ways — 2.4GHz dongle, Bluetooth 5.1, or wired USB-C — and NuPhy's own spec sheet lists a 1000Hz polling rate on both 2.4G and wired, but only 125Hz over Bluetooth, the same latency step-down most wireless boards have between modes. The keyboard runs on open QMK/VIA firmware rather than a proprietary app, so every key can be remapped and layered without NuPhy's own software. Battery life is rated up to 220 hours with the RGB backlight off, or 35–57 hours with it on, from a 4000mAh cell. It ships with 7 spare keycaps, 4 spare switches and a puller in the box, on top of the keyboard, cable and 2.4G receiver. Where NuPhy's own numbers get less consistent is customer sentiment: the product page shows 4.6/5 from 878 on-site reviews, but Trustpilot's rating for the whole store sits at 2.8/5 from 77 reviews, with some buyers reporting defective switches out of the box and uneven support for orders outside the US. Worth reading both before you decide.
Pros
- Hot-swappable low-profile switches — unusual for this thin a keyboard, most solder them in
- True 1000Hz polling on 2.4G and wired, not just a marketing number for one mode
- Open QMK/VIA firmware — full remapping without a proprietary app or account
- Up to 220 hours of battery life with the backlight off
- NuPhy runs an active Discord and r/NuPhy subreddit if you need setup help or troubleshooting beyond official support
- Ships with spare keycaps, spare switches and a puller included
Cons
- Bottom case is ABS plastic — only the top frame is aluminum
- Bluetooth mode drops to 125Hz polling, noticeably slower than 2.4G or wired
- On-site rating (4.6/5, 878 reviews) is much higher than Trustpilot's (2.8/5, 77 reviews) for the store — worth checking both
- Some third-party reviews report defective switches out of the box and mixed support for orders shipped outside the US
Who It's For
Good For
- Typists who want a slim, laptop-like feel without giving up swappable switches
- People who want open QMK/VIA remapping instead of a proprietary app
- Anyone who'll mainly use the 2.4G dongle or wired USB-C, not Bluetooth
Skip If
- You'll mostly run it over Bluetooth and need consistently low latency
- You want an all-metal build — the bottom case is ABS plastic, not aluminum
- You haven't yet compared NuPhy's on-site rating against Trustpilot's for this store
How It Compares: NuPhy Air75 V2 vs NuPhy Air75 V3
| Spec | NuPhy Air75 V2 | NuPhy Air75 V3 |
|---|---|---|
| Price | $129.95 | $139.95 |
| Battery (backlight off) | Up to 220 hrs | Up to 1,200 hrs |
| Battery (backlight on) | 35-57 hrs | 60-100 hrs |
| Bluetooth polling rate | 125Hz | 125Hz (unchanged) |
| Switch mount | Standard hot-swap | Gasket-mounted hot-swap |
| Extra control | None | Interchangeable functional knob |
| Typing angle | Fixed 3.5°/6.5°/8.5° feet | 3-stage kickstand 4°/8°/10° |
| Weight | 598g | 724g |
| Warranty | 1 year | 1 year |
| On-site rating | 4.6/5 (878 reviews) | 4.7/5 (604 reviews) |
V3 costs $10 more but delivers a huge battery-life jump (roughly 5x longer with the backlight off) plus a gasket-mounted feel and an interchangeable knob. Bluetooth is still capped at 125Hz on both, so that tradeoff doesn't change. If battery life and the knob matter to you, V3 is worth the premium; otherwise V2 is a proven, slightly cheaper board with more accumulated reviews.

Frequently Asked Questions
Is the NuPhy Air75 V2 hot-swappable?
Yes — every switch socket is hot-swappable, so you can pull the stock Gateron low-profile switches and swap in others without any soldering.
Does Bluetooth mode feel slower than the 2.4G dongle?
It can. NuPhy's own spec sheet lists a 1000Hz polling rate over 2.4G and wired USB-C, but only 125Hz over Bluetooth 5.1 — the same latency gap most wireless keyboards have between modes. For gaming or fast typing, use the 2.4G dongle instead of Bluetooth.
Verdict
On specs alone, the Air75 V2 is one of the more capable low-profile boards you can buy at this price: real hot-swap support, QMK/VIA, and a 1000Hz polling rate that most low-profile keyboards don't bother with. The catch isn't the hardware, it's the gap between how it's rated on NuPhy's own site versus Trustpilot — enough of a spread that it's worth reading a few outside reviews before you order, especially if you're outside the US where shipping and support experiences seem more mixed.
