Attention when buying bluetooth dongles
Recently, a friend of mine bought a bluetooth dongle.
In theory, it had an external antenna to enhance the signal.
Everything looked fine until the dongle fell down and the truth came up.
Wow, the expanded antenna was everything but to enhance the signal. Actually, it was nothing! Just a piece o plastic attached to the USB dongle bound to anything.
Dhammit! Take care next time you buy a bluetooth dongle....
