### ⭐⭐⭐⭐⭐ works well!
*by F***! on 29 April 2026*

works well with my aged laptop, does the job!

### ⭐⭐⭐⭐ This works well, but beware as I found that my Win 10 (Ver 1909) has gap in Bluetooth support
*by R***E on 25 April 2020*

There is nothing wrong with the product itself, and it ought to work well in plug and play with native drivers IF windows 10 Bluetooth support didn't let it down. That's apparently no fault of this product, though, so I haven't marked it down, and there is a workaround. 1) WHAT HAPPENED TO ME USING WIN10 PLUG AND PLAY: Product installs immediately. All drivers present and correct. Paired an audio speaker successfully. But wouldn't play, and in sound control panel it persistently said the device was 'disconnected'. The internet is absolutely full of people reporting exactly the same problem, and loads of suggested "solutions" that simply don't work - I tried most if not all of them! After further research - likely cause is that it seems until Win 8 Microsoft left it to hardware device suppliers to provide their own Bluetooth stack software, but from 8 onward Microsoft implemented a plug and play driver solution within windows itself. But this is inadequate/incomplete in some respects and they are currently working on completing it - no immediate solution therefore unless manufacturers provide 3rd party drivers. HOW I SOLVED IT EVENTUALLY: TP-Link claim to provide pre-Win8 drivers for the UB4a but the link on their website doesn't lead to drivers! However they often talk about UB400 at the same time, and UB400 does offer a driver in the support page for Win 7 and below. I decided to risk trying it with this product on Win 10. Result: it installed perfectly first time and the product now works with devices exactly as expected. You just have to right click the Bluetooth icon in the notification area to gain access to the Bluetooth functions, as obviously this software predates win10 and is not integrated into the win10 native bluetooth interface. The driver software is badged as "CSR Harmony Wireless Software Stack" and although it is a bit long in the tooth, it is a perfectly acceptable substitute until Microsoft get round to finally fixing their inbuilt bluetooth software stack driver. UPDATE: I need to revise the above having just taken delivery of super Bluetooth Headphones which I've reviewed elsewhere. These DID connect to this product when using Win10 plug and play mode without any additional driver. My previous attempts had been with an older Bluetooth cube speaker. So, as other reviewers have said - you might be lucky with plug and play. Seems this may depend on newness of Bluetooth item to be connected. Or, probably for older Bluetooth items, you may need to resort to the older driver as described above. I guess it is down to Windows not recognising/supporting older products - another example of software-driven product obsolescence keeping landfill busy and manufacturers happy. Well I don't give in that easily! My Bluetooth cube speaker lives to fight another day.
