High quality, very fast Bluetooth connection
Really good Bluetooth connection, allows me to connect my controller to my pc, no noticeable delay same with AirPods very good stable connection, very high quality. Just need a spare usb port so very easy to connect, cheap compared to quality, highly recommend. If you want high quality and speeds get this.

Works a Treat!
Worked straight out of the box, just had to pair it with my phone. No extra drivers needed (Windows 11).

Download drivers from their site
nice size, but for anyone struggling actually finding or connecting to devices you really need to download the latest drivers from the tp-link site, that fixes a lot of the problems

Actually very good. Usually usb BT adapters are spotty and withimited range. This is reliable and long range. Needs dedicated driver install but very solid

Setup issues and device incompatibility, lacking TP-Link polish
Note: I received this product as part of the Amazon Vine programme, in return for an honest and unbiased review. The opinions expressed below are my own and based on real-world use of the product. I thought setting this up would be a breeze. How wrong I was. Inside the box was a card instructing me to “Scan the QR-code for the setup guide”. So I did. The page it led to was a dead link. I therefore had to search for the drivers manually - UB600 drivers - download the correct package, and install. I first installed this on a laptop to test basic behaviour and functionality. After a reboot, everything appeared to be working. Or so I thought. I was unable to properly pair either my Samsung S26 Ultra phone or S10 FE Plus tablet. Windows would report that pairing was complete, briefly show “connected”, and then immediately revert to “not connected”. Assuming a potential conflict with the laptop’s built-in Bluetooth, I moved the dongle to its permanent location - an older desktop PC with no existing Bluetooth. Unfortunately, the same behaviour occurred on the desktop. In an attempt to force a connection, I tried initiating a file transfer from the PC to the phone, which eventually did start transferring, but only after a flood of repeated pairing prompts requiring constant confirmation. This is clearly not expected behaviour. Even at this price point, that level of inconsistency is difficult to overlook. For reference, both the PC and the laptop are running the same OS version (Windows 11 version 25H2, OS Build 26200.8457). By contrast, standard peripherals - mouse, controller and earbuds - paired at the first attempt, although there were occasional audio dropouts and moments where input became unresponsive. This was resolved by using a short USB extension cable to move the dongle away from the USB port on the back of the PC. Once repositioned, responsiveness and stability improved noticeably. This is likely one of the trade-offs of the nano form factor, where antenna placement is inherently constrained. That same form factor is unquestionably excellent for space saving, but it is so small that it’s easy to misplace if it needs to be moved between devices. A simple addition such as a cap with a keyring loop would have improved usability without compromising the compact design. If everything worked as it should, this would be an instant recommendation, especially at such an inexpensive and appealing price. But while it does fulfil its intended role on the desktop PC for my use case (and lack of phone/tablet compatibility is not a dealbreaker there), the incompatibility with certain devices and the dead link in the setup instructions are not what I would normally expect from TP-Link. As such, for me, this is a rare miss.

Une clé Bluetooth pratique et efficace
Je suis très satisfait de cet adaptateur Bluetooth TP-Link UB400. Il est facile à installer, il suffit de le brancher sur un port USB et il est reconnu automatiquement par Windows. Il me permet de connecter des périphériques Bluetooth à mon PC, comme des manettes, des casques ou des enceintes. La qualité du son et du signal est bonne, je n'ai pas constaté de coupures ou de latences. La portée est correcte, je peux écouter de la musique jusqu'à 10 mètres de distance. En revanche, faites attention à ce que vous branchez sur le port USB voisin, car cela peut causer des interférences et rendre la connexion Bluetooth capricieuse. Le seul point négatif que je pourrais mentionner est que la clé est assez petite et qu'elle dépasse un peu du port USB. Il faut donc faire attention à ne pas la perdre ou à ne pas l'abîmer en transportant son ordinateur. Je conseille donc de la ranger dans un endroit sûr quand on ne l'utilise pas. Je recommande donc cet adaptateur Bluetooth à tous ceux qui veulent équiper leur PC d'une fonctionnalité Bluetooth sans se ruiner ni se compliquer la vie. C'est un produit simple, efficace et fiable.
