As always quickly sent Amazon and neatly packed but brauchtt you not to write here :-) My problem has been that I wanted to send my bluetoth to meinerr stereo music from my laptop. Said done Logitech Audio Bluetooth Adapter ordered. But the Blutooth power was limited in two ways, sound quality and in terms of transmit power. 3 meters croak no sound more Aussetzer.Gembird mini 2 ordered, BlueSoleil installed, enter the password for the Logitech adapter, and set the Bluetooth transmission in the Windows speaker settings and finally super sound quality and I can with the doors closed in my old apartment no matter where I stand or sit to play music. But I think the 100m are somewhat exaggerated in an apartment :-) except there are no walls :-) Otherwise super simple product to the ever-popular Windows 7
