I bought this a few weeks ago and stick'm perfectly happy until now. I connected it to a USB port on my Dell monitor. Was unhesitatingly recognized by Windows XP SP2. Embed had no driver manually etc. After the drive is successfully detected, I have my SE K800i which was connected to the drive without any problems. I can even automatically create a "handshake key". I do not know whether the two devices via Bluetooth 2.0 to communicate, in any case, the transfer speed is not felt very much slower than USB 2.0
I have also printed with this stick via Bluetooth on Lexmark printers. Also no problems in the issue or transfer.
Can only recommend to owners of SE K800i or people who just want to print via Bluetooth to stick.
