I received the Bluetooth USB dongle on time from the vendor. Unfortunately, although it appeared to work correctly (Win7 64bit recognized and automatically installed drivers with success), it failed to "see" any of my devices, and viceversa. I contacted the vendor, which was very polite and responded quickly, mentioned that faulty items were very rare and would send a replacement immediately. It arrived eventually and this one did work correctly, again being recognized by Win7 and pairing my devices with no hassle.
The dongle comes with a CD including the BlueSoleil bluetooth suite, but unfortunately it's only 32 bit.
I'm giving 4 stars due to the first faulty device and the unusable bundled software, but I do recommend buying it considering its ridiculously low price, great vendor support and functionality once i got it working.
