I use the product to an Apple Bluetooth wireless keyboard inputs to receive and this for about 3 weeks. This works perfectly.
Only the "wake up" from standby mode using the keyboard is not possible for me.
Installation of the Bluetooth sticks went on Windows 7 and XP fast and easy.
However, I strongly advise them from the supplied software to install. Through this, it no longer worked and easy uninstallation could not fix this. Only a Panel Reset the system to a previous point in time and a renewed! Driver Installation! fixed the problem.
If this is taken into account, I would recommend this product highly, even in the face of the good price-performance ratio.
Although the software product negatively influenced and it should normally be a matter of course it all works, I evaluate the product with 5 stars, as would have yielded a glimpse the software is not really more power and possibilities in comparison converters for operating without them.
