The USW-Flex-Mini is an excellent little switch for expanding a UniFi network. Despite its small size, it offers full Layer 2 managed functionality via the UniFi Controller, making it perfect for home labs, smart home gear, or extending wired connectivity in tight spaces. Setup is simple — just adopt it like any other UniFi device. Once added, you get full control over VLANs, port profiles, and monitoring. It runs completely silent (fanless), and the metal chassis feels solid and well-built. Power can be supplied via USB-C or 802.3af PoE — I use PoE from another UniFi switch to avoid extra cabling. Throughput is consistent and reliable, even under load. If you're already in the UniFi ecosystem and want a clean, reliable switch with full controller integration, the USW-Flex-Mini is a no-brainer.

Built to Ubiquiti's high standards and well-presented in it's (still-sealed) box, this device is minute. I thought that the Netgear device it was replacing was small, but this is even smaller! Unlike the Netgear, this does not have mounting slots on its base for screws, so cannot be fixed to the rear of a desk or cabinet - that said, it's small enough to allow the use of double-sided tape, provided the surface being fixed to was flat and dust-free. There have been comments made by some reviewers that it lacks POE passthrough - this would not be possible, as loading all four of its ports to the maximum power would overload the power capabilities of not only the units Port 1, but also the upstream device, as well as result in significant volt drops down the network cable. Some might think that the solution to this would be to use the external power supply; this will not work either, as the external power feed is 5Vdc - but the POE voltage is circa 50Vdc, thus removing the capability to use USB and requiring a far larger mains power supply. When supplied, I attached it to my existing network and it immediately showed in the device list, with a status of 'Pending Adoption'. I selected Adopt, it was then added to the existing install, checked for a firmware update (there was) and installed same, restarting once complete - all in all, utterly painless. First impressions - an excellent device, superb value for money. From a functional perspective, it does very well what it's supposed to do, with LED's on the individual ports for status, which are mirrored on the cloud management system.

Got this to extend my UDM Pro's reach with a couple additional devices farther away, and I have to say it does not get simpler than this. I got a couple sockets with 5V regular usb ports and plugged in works just fine! The cable it came with originally is a 2 pin shaver socket cable, so not the 3 pin one unfortunately, but this at least keeps down the plugs in my socket! Just grabbed a regular old type-c to usb cable plugged it in, turned on the port on my UDM pro, and it instantly showed up for adoption. After adopting it did a firmware update (took like 1min or so), and it had its own ip assigned from my dhcp server without a single setting needing to be changed. Of course you would want this switch to have a fixed up so just set that up outside of your DHCP range and you are good to go! Port control also works flawlessly, I am using tagged VLANs for IoT Devices and my main network, and both work flawlessly. It does allow having 2 vlans on the same port even though it says "limited functionality" in the settings page. Its compact, smaller than expected, but you cannot fault it how easy it is to set up and put it in a corner with fairly good airflow. I will just keep the original power cable in case I ever decide to get an adapter and use that, but until then the type-c wall plug works wonderfully. Ports can be individually disabled / enabled and statistics show in the controller hub just fine!

I've got a few other Ubiquiti products and was looking for a cheap switch for my office which has a few more devices than it used to thanks to working from home. I did have an old Netgear switch but decided to pick up a Ubiquiti device but didn't want another full size 8 port switch. As a basic switch it does what it says on the tin and was immediately detected by my Ubiquiti controller and once adopted looks like any other Ubiquiti switch with the exception that some stats aren't available and some are not real time. The switch itself is very small, less than half the size of the old Netgear 8 port switch that was on my desk. It can be powered either by USB-C or via PoE but it's worth noting that the bundled power supply is a European version but as it's just standard USB-C it's easy enough to use something else or use PoE if you want. Personally I would have preferred if the USB-C power supply had a detachable cable which would make the process easier of swapping to another plug and really the lack of UK or even just a standard USB-C cable is the only thing that lets it down. I happened to have one going spare but not everyone will. If you're planning on using PoE to drive it then you've got no worries though but remember that this is PoE to power the device only and it will not passthrough.

A brilliant switch. Adopts immediately to your current Unifi network. I got this to further increase ethernet connectivity in my son's bedroom. He currently has ethernet in his room connected to a console and wanted another console for Christmas and this switch was needed so that both consoles can connect to ethernet. As his ethernet is running from a POE switch this flex mini is powered by POE rather than using the USB C for power. The USB C lead came with an EU plug rather than a UK one for some reason however as mentioned this is powered in my network by POE. It's small and powerful and ideal to increase connectivity in your Unifi network. Definitely recommended .

Unlike most other Ubiquiti products this is rather cheap however still a great product. Used it as a switch behind a TV for all the video stuff (TV, Nvidia Shield, gaming console). Really small, size of a deck of cards. Powered via POE from my Ubiquiti UDR so takes up even less space as it doesn't need it's own power supply. Very easy to adopt into Unifi controller. It is still a managed switch meaning that you can select a VLAN for every port individually. HOWEVER, it does not support custom VLAN profiles. For example, each port can carry either all traffic or you can pick a single VLAN. However, it cannot carry a custom profile consisting of 2 or more specific VLANs. I imagine that most people will be using for a similar basic setup as mine so this is not a big deal.

Got this to connect to a Raspberry Pi Cluster (UCTRONICS 4 Pi Cluster) U6244. I was originally using a TP-link managed switch but that did not play well with my existing UniFi networks (VLAN tagging did not interoperate) ... so went with this. Amazing little piece of kit, just plug and play (if you have Unifi powered netwrok (UDM Pro, Cloud controller). Powered via POE. Can tag any of the ports as any VLAN, can isolate each port from each other even if on same VLAN. Really good piece of kit. I am going to be replaceing all my other 4 port netgears or TP-links throughout the house with these. The ONLY downside is that it is POE in only. The 4 'output' ports are NOT POE.

Terrible, tardo varios dias en llegar poco mas de un mes, encima la publicacion dice que son 5 unidades y solo recibi 1! El producto es genuino de ubiquiti y venia cerrado pero la publicacion y tiempos de entrega no cumplieron

J’utilise le Ubiquiti UniFi Switch USW Flex Mini depuis un certain temps et j’en suis très satisfait. Malgré son format compact, il offre d’excellentes performances et une stabilité exemplaire. L’intégration dans l’écosystème UniFi se fait sans aucun problème : tout est détecté et configuré automatiquement via le contrôleur. La gestion via l’application est claire et fluide, parfaite pour surveiller ou ajuster le réseau à distance. L’alimentation PoE est un vrai plus : elle simplifie grandement l’installation en évitant d’avoir à tirer un câble d’alimentation supplémentaire. Un petit switch gigabit fiable, silencieux et bien pensé — idéal pour une installation prêt de la télévision ou dans le bureau. Très bon rapport qualité-prix, fidèle à la qualité Ubiquiti !

Świetny, kompaktowy switch od Ubiquiti — działa bardzo stabilnie, łatwy w konfiguracji i idealnie współpracuje z systemem UniFi. Doskonały wybór do domowej lub małej biurowej sieci.

Ich habe meinen alten unmanaged Netgear-Switch gegen den USW-Flex-Mini getauscht und bin sehr zufrieden. Der Switch lässt sich nahtlos in UniFi OS einbinden; die VLAN-Konfiguration ist damit wirklich kinderleicht – ideal, wenn man sein Heimnetz sauber segmentieren möchte. Besonders praktisch: Der Flex-Mini kann per PoE von meiner UDM SE versorgt werden, was Kabelsalat reduziert und die Platzierung flexibler macht. Für den Preis bekommt man einen leisen, zuverlässigen 5-Port-Gigabit-Switch mit allen wichtigen Managed-Funktionen im UniFi-Ökosystem. Pro: Einfache Einrichtung & Verwaltung über UniFi OS PoE-Versorgung über UDM SE funktioniert einwandfrei Kompakt, leise und stromsparend Sehr gutes Preis-Leistungs-Verhältnis Contra: Kein PoE-Out (nur Versorgung per PoE/USB-C) Fazit: Klare Empfehlung für alle, die von einem einfachen Switch auf Managed-Funktionen umsteigen und bereits UniFi nutzen. Für den Preis fast unschlagbar.

Works great. Last one got taken out by lightning. Easy to install and incorporate to our system. Basically plug and play if you run Ubiquity. No issues with speed or heat build up.
