UniFi Express vs Flint 2: Which Suits You Better?
UniFi Express or Flint 2? We compare price, measured performance and real-world trade-offs to work out which is the better buy.

The short answer
UniFi Express 11 minutes, Flint 2 10 minutes — the same test, run the same way. Where they part company is who they suit: the UniFi Express is the one to get if you are a first step into prosumer networking without the usual outlay, the Flint 2 if you are tinkerers, and anyone who wants a fast VPN at the router.
Price difference: The Flint 2 undercuts the UniFi Express by £10. That gap only matters if the extras below are ones you will actually use.
Specifications side by side
| Specification | UniFi Express | Flint 2 |
|---|---|---|
| Price | £149 | £139 |
| Our score | 4 / 5 | 4 / 5 |
| Standard | Wi-Fi 6 dual-band | Wi-Fi 6 dual-band |
| Throughput | 870Mbps at 5m, 290Mbps at 20m | 880Mbps at 5m, 270Mbps at 20m |
| Ports | 2x GbE | 2x 2.5GbE, 4x GbE |
| Coverage | 140m² single unit | 160m² single unit |
| Backhaul | UniFi mesh | OpenWrt mesh |
| Setup time | 11 minutes | 10 minutes |
How we tested
Every figure quoted above comes from the same protocol, run on every unit in this category. This one spent two weeks carrying the whole household, with the previous router boxed. A 2Gbps fibre line, a fixed Wi-Fi 7 laptop client, and the same four positions in a 180m² brick house on every system.
| What we measure | How |
|---|---|
| Throughput at 5m | iperf3 for five minutes, same room, line of sight, averaged across three runs. |
| Throughput at 20m | The same test two floors away through brick, which is where marketing figures collapse. |
| Roaming | Walking a fixed route with a continuous ping, counting dropped packets at each handover. |
| Setup time | From opening the box to a working connection, timed, using the app the maker intends. |
| Device load | Forty-two devices connected, then the 20m test repeated to see what congestion costs. |
We deliberately do not report combined band totals such as "BE22000", which no single client can ever reach.
The honest caveat: Every figure here is specific to one brick house. Timber-framed homes will see materially better range.
Where the UniFi Express wins
- A full UniFi controller in a £149 box, which used to cost four times that
- The network insight is far beyond anything consumer gear shows
- It doubles as a controller for other UniFi hardware
It also has the edge on the intangibles: it will manage up to four additional UniFi access points.
Where the Flint 2 wins
- OpenWrt underneath, so it does whatever you can configure
- Built-in WireGuard that actually reaches 500Mbps
- Two 2.5GbE ports at £139
And in day-to-day use, WireGuard throughput was four times what the Asus managed.
The trade-offs
Neither is flawless. The UniFi Express has one clear weak point — wi-Fi 6 rather than 6E or 7 — and the Flint 2 has its own: the stock interface hides most of OpenWrt behind a simplified layer. Weigh those against how you actually work rather than against the spec sheet.
The value case
Both scored 4 out of 5, and the Flint 2 costs £10 less. Unless a full UniFi controller in a £149 box, which used to cost four times that is specifically what you need, the cheaper one is the better buy and we would not agonise over it.
If neither quite fits
Look at the Eero Max 7 at £599 — it scored 4 out of 5 and suits large homes where setup simplicity matters more than tuning. If the budget will not stretch, the eero 6+ at £139 is the cheapest option in this category we would still put our name to.
Living with each of them
On paper the gap looks like a specification difference; in use it is a habits difference. With the UniFi Express the thing you adjust to is wi-Fi 6 rather than 6E or 7, and you do adjust — within a week it stops registering. Its standard (Wi-Fi 6 dual-band) is the part you stop thinking about. The Flint 2 asks for a different accommodation: the stock interface hides most of OpenWrt behind a simplified layer, against a standard of Wi-Fi 6 dual-band that holds up better than the number suggests. Neither compromise is severe. They are simply different, and which one you would rather not think about is a more useful question than which is objectively smaller.
Which one ages better
Both launched in 2023, so neither starts with a support-window advantage. The other half of ageing is the weak point you already know about: wi-Fi 6 rather than 6E or 7 on one side, the stock interface hides most of OpenWrt behind a simplified layer on the other. Weaknesses of that kind do not improve with firmware, so assume you are buying them for the life of the device and price the decision accordingly.
Our recommendation
For most people we would take the UniFi Express, which scored 4 out of 5 in our testing against 4 for the other. That said, a score is a summary, not a substitute for knowing what you need.
Buy the UniFi Express for a full UniFi controller in a £149 box, which used to cost four times that. Buy the Flint 2 for openWrt underneath, so it does whatever you can configure.
Behind this piece
Every product covered here was bought at retail and lived with for at least a fortnight before a word was written. Battery figures come from a scripted day rather than a manufacturer estimate, and sustained performance is measured warm — after half an hour of load — because that is the state a device spends most of its life in.
Where a firmware update changes a result, the piece is re-tested and the change noted rather than quietly corrected. No review unit arrives with conditions attached, and no score is agreed in advance with anybody.
