It took me forever to figure out how to install it (about a week of searching online), but I finally managed to get it working perfectly. I don't know how it worked for many users without having to do anything... for me, it was the opposite!

I bought it for a very specific purpose, but I will leave a comment to help anyone looking for the same solution as me.

I bought it exclusively to connect Nintendo Switch controllers to the Yuzu emulator, which now fully supports them. Unfortunately, for the purpose I got it, it has a very short range, we're talking about 1-1.5m max to avoid noticeable latency or disconnection (at least in my case). If I exceed the limit, there is a significant delay (>900ms-1.5sec) as well as missed button presses. However, the connection of the adapter was plug and play on a Windows 10 system and in games where I exclusively need motion controls, such as Just Dance or Arms, it does its job perfectly.

I should mention that in a test connection with a soundbar in my living room (Lg SJ4) at 5 meters without obstacles, it worked flawlessly.

I immediately noticed the computer, the headphones (https://www.skroutz.gr/s/25123615/Edifier-X5-%CE%9C%CE%B1%CF%8D%CF%81%CE%BF-%CE%BC%CE%B5-6-%CF%8E%CF%81%CE%B5%CF%82-%CF%87%CF%81%CF%8C%CE%BD%CE%BF-%CE%BB%CE%B5%CE%B9%CF%84%CE%BF%CF%85%CF%81%CE%B3%CE%AF%CE%B1%CF%82.html#specs) connected easily and I have no problems with disconnections, but there is a noticeable delay in the sound, despite both the dongle and the headphones having aptX technology! I tried installing the accompanying software, but I didn't see any improvement.

In a desktop computer, it had some interruptions and I have to be next to it to listen without interruptions (Bluetooth headphones). So-so.

It works as it should without any disconnections, etc. on a stationary PC, both directly and through a hub.

The only problem I had was that once it connected to a USB 3.0 hub monitor and instead of being recognized, it drew a lot of power and increased the temperature. After restarting everything, it worked normally and it didn't get burned. The same problem did not occur again.

I think the range it states is a bit "optimistic".

Finds devices but the connection is terrible - it keeps disconnecting and it's weak, even if the device is placed next to it!!!

Very reasonable price, works out of the box on Win10 (no need to do/download/install anything) and that's where the good things end.

Whether it has interruptions in sound even when the Bluetooth device (headphones, speakers, etc.) is one meter away depends directly on what is connected. For example, with Fender Newport speakers, it's okay, but with JBL E45BT, it's a disaster (while the same headphones with Taotronics and from a greater distance have no issues).

It connects directly to the computer, even on Windows 7 that I have. The only problem is with some devices that want to connect close to it.

Pros: Connection speed, weight, size

Cons: Range, signal loss when there is an obstacle

Two pieces were purchased, only for connection with Lego Spike Prime. Only for this!!!
They were connected to Dell Optiplex 9010 Win10 (USB2.0) and to Macbook Pro (USB3.0).

On Dell, it worked immediately. Windows drivers. Connected to Spike. After a restart, it didn't connect.
Uninstalled and reinstalled, and it worked again (and now it works).
On MBP, it didn't "work". A "disabling" process of the built-in Bluetooth had to be done through the terminal.
Overall, satisfied.

As soon as I connected it to the computer, it immediately recognized it and installed its own drivers. The sound quality is very good, better than I expected for a 10 euro USB stick. In terms of range, it reaches about 5-6 meters outside the room with my JBL T460BT Black, which is very good for me. Highly recommended, 100% from me

Flawless. No need for driver installation, just plug and play ;). Connecting with Apple Airpods 2 is ridiculously easy - that's actually why I bought it. Sometimes the sound has a slight interference, but it's so rare that it doesn't bother you.

I made the mistake of installing its own driver (from the internet). When I saw the results, I uninstalled it and let Windows choose the driver. Now everything is working smoothly.

I wanted to get an Asus, but I chose this one because of the good reviews. It's just okay.

More specifically:

* It takes a long time to find the device many times, but once it finds it, the signal doesn't drop.
* It frustrated me trying to make it work properly on Windows 10, as initially it only worked with its own software. It's better to let Windows Update search for the drivers so that it can integrate it into the system.
* I also tried it on Windows 7, and it does the same things as with Windows 10.

The only device I have tried is the Xiaomi Redmi AirDots that I have, and while they play music just fine, their microphone doesn't work.

I bought it for connection with a radio amplifier. It connects normally and relatively easily with all BT devices. It doesn't work for me on USB 3.1 and it's difficult to connect when I plug it into the back port. The first issue may be due to my PC, while the second one may be due to the range of the sound system. However, the range I need is five meters without obstacles, and when I close the intermediate door, it loses the signal. The CSR4.0 chipset is accompanied by software that does a very good and relatively easy job. I say this because I initially bought another one with the same chipset for €5, but it didn't come with software, and after struggling for a week when it felt like it, I returned it. Also, the included software has many functions and customization options, not only for the sound system. I recommend it.

Very good adapter. As soon as you connect it, Windows 10 automatically recognizes it and you can use it immediately without installing drivers. I bought it to connect the controllers of the Lenovo explorer on top.
