Blue Tooth connector for USB

After I read some recessions by other Bluetooth USB sticks, I decided for this because the price was very attractive and the product of a brand manufacturers and is well mastered all currently popular Bluetooth standards.

I was aware in advance that the stick will be very small, but that it is so small, I did not think;) The entire unit is just as big as a thumb nail, but still has a grip bezel, so you him easily can fiddle again without removing large. The "size" has another advantage, you can even use both ports at closely spaced USB ports, because the stick allows enough space for the other port (which is often the problem with USB flash drive is).

Below are the installation instructions (in about 25 languages) 2 Mini-CDs with a Bluetooth "software", the other with the operating instructions as PDF. The installation went smoothly under Windows Vista Home Premium 64-bit.

My Sony Ericsson K330 mobile phone is easily recognized, which I think is just a bit annoying that you have to put in any file download always on the Bluetooth icon in the taskbar, the PC in the "receive mode". Maybe it goes well with third-party software, since I'm not so versed what Bluetooth devices terms and this is my first experience in this field, I would not exclude it. I would have just wanted an easier way of file exchange (Explorer or Total Commander similar), but it still works, albeit a little more complicated. It is probably on my phone when I got it right it would probably be easier if it would support PAN (Bluetooth Personal Area Network).

The remaining Bluetooth functionality I did not use because I only option sought images that were created with the internal camera of the mobile phone to be transferred to the PC. The stick was working here without any problems in a non-powered USB Hub. All in all a functioning branded product at a fair price.
