It works without problems, but as a construction, it is not very good. The movement it has is not very easy and requires care not to break.

I was slow to connect it with the headphones.... I turned off the Bluetooth on my phone and the CONNECTION OF HEADPHONES WITH THE USB ON PC worked.

It does not make good contact with the computer ports. Due to its dual USB A & USB C feature, they do not align correctly and it has a lot of "play". As a result, it disconnects very frequently.

The product does its job, it is plug and play for Windows 10, as soon as you connect it, the drivers are automatically installed by Windows and you're ready to go. The connection with peripherals is seamless.

The only downside is that compared to, for example, the Bluetooth (4.0) of an old Xiaomi mobile phone that I have, it has a shorter range and slightly higher latency in audio transmission, so I don't know if it's the best value purchase for €10, but in terms of connection stability when you're close, it's excellent.

+ Easy installation
+ Connection stability
- Range (compared to mobile phones)

In Windows 10, it was immediately recognized as a device. However, in order to "see" the external Bluetooth devices that I wanted to connect (some wireless headphones) to the computer, I had to install the drivers from the manufacturer here: http://downloads.2direct.de/treiber/BT0054.zip

Here is the product page: https://www.2direct.de/en/audio-video/bluetooth-wireless-adapters/4574/bluetooth-5.0-adapter-usb-3.2-usb-a-and-usb-c?number=BT0054

I bought it for use on a Linux desktop. Unfortunately, it is not plug and play and requires the Realtek rtl8761b-fw firmware to work. If someone is using an Arch-based distro, they can find it here https://aur.archlinux.org/packages/rtl8761usb/. There is a guide for Raspberry Pi here https://www.raspberrypi.org/forums/viewtopic.php?t=294634, but I haven't tried it. The range seems to be about the same when using headphones as with the previous Bluetooth adapter (konig 200) that I had with version 4.0.

I bought this product because it supports Bluetooth 5.0 and it was the only option I saw. I have had it for about a week and I have tested it with Bluetooth headphones and speakers on Windows 10. I did not encounter any problems or disconnections. The computer recognized it directly, although you can also find drivers through Logilink. It is not particularly large considering that it connects via USB A and USB C, it protrudes about 3-3.5 centimeters from the port. The manufacturer claims a range of 10 meters, but I had issues even with a wall in between and I doubt it is still valid even without a wall. However, I consider it to work properly up to 8m, especially if you are next to the computer. At 13.5 euros, I wouldn't call it cheap, but I definitely don't regret buying it for what it offers. I recommend it.
