For Windows I needed to install the manufacturer's software and it worked well. For Linux you have not even needed to install anything (Ubuntu 18.04): just connecting it to the computer has activated the Bluetooth icon as if it is integrated into the computer and it worked perfectly.
It works fine but when playing movies or playing it is about 2 seconds late since it does not have aptx but well, I guess so. Otherwise it works very well has never been disconnected, it's very stable and I can send my mobile files to pc and pc to mobile. In addition to connecting bluetooth controllers, headphones, keyboards, mice and everything works very well although as for controls and some keyboards you can see the imbug lag but it is minimum. Finally Great per duct but better go for one with apxt or some similar technology that removes the impug lag almost completely.
Ah and also on Windows 10 it's just connecting and using no drivers or weird moves since it's plug and play.
The package was packed safely so that the inside would not be damaged. Fast shipping. Bluetooth very easy to use, although it comes with intrusion manual, on my pc i just plugged it in and it worked. I use it to listen to videos on the pc with airpods wireless headphones and it works great. I'm so glad.
All perfect, nicely packed, with QR instructions and code for web link. A 10 without testing transfers. I had to install the codecs, my PC didn't recognize it. I have Windows 8.1 installed. More comments when you try 100%.
