Correct product
Allows to have bluetooth and wifi without monopolizing USB ports. But the assembly is not very simple. The holes in the case have a flat to avoid the connectors to turn ... but they are round without flat. So you have to machine the case a bit with a file! Not so good. Then of course when you tighten it, you need a second one because they turn.
The card is to be put first, contrary to the assembly instructions. The connections on the card are microscopic and require a bit of skill. There are cables of different lengths, so follow the instructions even if they are quite surprising. The cables are much too long and you have to find a place for them.
In the end it works, except for a problem with the recognition of the wifi whose SSID is hidden. I don't know if it's the card or the box, but there's no way around it. I had to unmask my network.
