I have this micro USB Bluetooth adapter purchased to my previously unable to connect Bluetooth-enabled laptop with my smartphone. So I want to share files easily, having to connect a cable each time. The installation works without problems and the Adaper is ready for use quickly. The coupling with the smartphone has worked very well.
Equipped is the adapter with the new Bluetooth 4.0 technology, but it is also backward compatible. This then also older devices can be used. Prima, I find that the adapter really is quite small and even plugged hardly noticeable. So you can carry the laptop also good without every having to remove the adapter. Energy saving is the thing and still be according to the manufacturer. What more do you want? But there's me then 5 star and a buy recommendation.
