Excellent bit of kit
My laptop decided it didn’t like the Bluetooth driver anymore and so parted ways with it out of nowhere. It works fine otherwise so I didn’t want to replace the whole thing. This adapter was a little tricky to set up, but I’ve had it for almost a week now and it works perfectly. I have had no connectivity issues, and my laptop seems to be very happy with it so far. It’s a shame that it has to take up one of my USB slots but honestly it’s a small price to pay to have working Bluetooth! The adapter itself is small and seems to be very well-built, and from what I can tell it has decent range (better than the inbuilt Bluetooth!) not that I stray very far from the screen at any time

Expensive but reliable
Of course, you can buy bluetooth receivers from other brands which do the same thing, but if you want a strong connection that supports 4 Xbox controllers for game evenings (in my case), it might be worth more money to buy this keeping in mind the quality of the adapter and its lifetime as opposed to others. There is virtually no latency when using this and the drivers were easy to set up for me on Windows 11. The Bluetooth connection is reliable. I can't speak for the range as I live in an apartment, but we have had no issues with it disconnecting so far. Hence, high quality but for a price.

Works great with PS5 controller and wireless keyboard/mouse
I bought this after getting a new (and not cheap!) gaming PC, only to realise it didn’t have Bluetooth. This little adapter sorted that straight away. I use it to connect my PS5 controller, wireless keyboard, and mouse - all work perfectly with no lag or dropouts. It was literally plug and play - straight in and working within seconds. Range is fine for my setup, though it’s definitely better plugged into a front USB 3.0 port rather than round the back. It’s small, reliable, and feels well made. Not the cheapest option, but you can tell it’s good quality with the response time being like wired! Highly recommend

Great Bluetooth adapter
It worked very well. The connection was always stable. And it is discrete due to its size. I was very happy with this product.

Doesn’t work well with headphones
This device is plug-and-play for windows devices therefore is very easy to setup. However, the Bluetooth signal is quite weak, so don’t expect to be able to use Bluetooth headphones with it. It works perfectly with gamepad controllers which is what I bought it for. Signal strength: 2/5 Ease of use: 4/5 Value for money: 3/5 Overall: 3/5

Absolutely essential for me
I play PC games and prefer to use the PS5 Dualsense controller. IMO it is better than the Xbox controller. I already have BT on my PC but the Dualsense keeps playing up. The buttons become unresponsive or the camera just rotates all over the place. At first I thought the Dualsense and PC were not not very compatible compared to the Xbox controller. Maybe it is. Anway, I have been using my Dualsense almost everyday for the last couple of weeks and I have not had a single issue. No disconnects! The BT dongle is great. Either by built in BT is crap or there is interference. I have the USB dongle on top of my PC so I guess there is a direct line of sight between it and my controller.

Doesn't even come close to expected performance. On laptop and desktop it tops at 300Mbs where it should be in the thousand+ range. Singal used for both end devices was full strength to an Asus router (BE10). The laptop using its built in 6E card gets 1400Mb/s and the desktop on its built in Wifi 6 card gets around 1000Mb/s so this thing at 300/350 is appalling. Utter trash.

Its one of those invisible devices. My desktop did not have Bluetooth, I plugged it in and forgot about it. There was nothing to install and configure, it was pure plug and play on Windows 11, after i inserted it into an empty USB slot my Device now had Bluetooth, simple as that..

Ürün tak çalıştır olduğu gibi istenirse internet sitesinden yazılımı da indirilip yüklenebilir. Bu işlemle beraber cihaz daha stabil çalışır hale geliyor. Ancak bunu yapmadan da kullanmakta bir problem yok yine bütün fonksiyonların gerçekleştirebiliyor.

Works fine with Linux (Zorin OS), plug and play! Inclusing with AirPods.

Fungerar inte. Tappar ständigt signal. Den är helt värdelös och känns väldigt dåligt byggd. Sök bättre alternativ!
