good product, but I can say the range is very small. I go to the bathroom, it loses signal, I go to the kitchen, it loses signal, generally I expected a stronger signal.

It arrived quickly and solved my problem of connecting Bluetooth speakers to a computer with Linux Mint.

Range that goes through multiple walls, 0 latency (I can't even notice it unlike the built-in Bluetooth of the Intel WiFi card on my desktop), incredibly durable (it survived 2 months inside a dryer/washing machine with multiple washes and drying cycles in water, 1400rpm spins and temperatures over 90 degrees (I had forgotten it in a pocket and it fell into a gap in the drum) and it still works perfectly.

It was installed on Windows 11 without any issues at all to connect PS4 and PS5 controllers to the PC, giving me greater range and I achieved that. At about 5 meters distance with obstacles in between, the connection is perfect.

I bought it to be able to connect the PS VR2 to the computer to see the controllers, and it works perfectly with multiple devices connected together.

Definitely not a 40m range, I would say less than half. However, it does not interrupt at all, I use it to connect headphones to the computer and it works continuously for hours without interruptions. When I go to another room, I can hear from the headphones, but with difficulty they can hear me when I speak.

It worked for 4 days with a range of 7 meters in an open field and never turned on again,,,,,
Waste of money...

Excellent signal, I have tested it with PS4 controllers using DS4Windows for hours without any lag or disconnection. It also doesn't get confused on Windows 10 with multiple controllers being connected/disconnected

It worked perfectly for connecting the computer to the 1Mii Bluetooth audio receiver 5.1 on the stereo with satisfactory sound quality.

I got it to listen with the Galaxy Buds Live from my PC (sometimes I don't want to bother my wife).
I plugged it into the USB-5 port on the monitor. Windows 10 recognized it immediately without any problems. With the headphones, everything is great. Its range is very satisfactory, as I can hear perfectly wherever I am in the house. And I mean distances of at least 7m-8m in a straight line with walls in between... I admit I didn't expect that.
I highly recommend it.

It was installed on a laptop with Windows 11. It was immediately recognized as hardware, without manual driver installation (probably the system downloaded them automatically). Very fast and uninterrupted connection with devices (headphones, sound system). Overall, it is a quality accessory and seems to be doing its job very well at the moment. Recommended!

You need to install the latest drivers from the Asus website in order for it to work properly on W10

Relatively stable but not as long range as I would expect. I bought it thinking it was the best I could find through Scroutz for around 20 euros, but in the end, with a simple wooden coffee table in the middle, it loses signal if I go beyond 2.5 meters.

I had bought it to connect my wireless headphones to my PC. It works perfectly in any case, except when you want to play a game. There is a split second delay, which makes them a bit useless for gaming. However, for movies, videos, communication, etc. it is the best, in fact, it provides better sound quality than the one provided by the aux

I ended up with this specific Bluetooth adapter after a little research, as many articles and people recommended it. I needed a Bluetooth adapter for my desktop computer (because it didn't have built-in Bluetooth) to connect wireless controllers so that I could play games with friends on my PC.

I consider its price to be excellent for what it offers in terms of quality, especially with the new Bluetooth 5.0 (fast speeds, range)!

It arrived and as soon as I plugged it into the port, it was recognized immediately and ready to use (Windows 10 64-bit). I went to download the latest driver from the official site (not that it was necessary).

Currently, I have connected two controllers to it [soon to be four], and everything is working perfectly!

Microsoft Bluetooth mouse purchased 2 years ago and another Microsoft Bluetooth mouse purchased together with the BT500 adapter have interruptions every 2 minutes or so. The same mice work smoothly with the USB-BT400 adapter. Obviously, they are not compatible with Bluetooth 5.
