First observation, the key is actually tiny. Ideal for connecting it to the back of my tower PC. After installing the software (driver) on Win7 64b with the supplied CD, comes the testing phase send / file recovery. And this is where things get tricky: almost impossible to access the contents of the phone (long access), not intuitive procedure to send or receive files (I spent nearly 1/4 hour for every set properly groped by here and there). Ultimately, the flow is more than average (about 20 s to send a picture of 1.5 MB). But this must be related to the bluetooth technology. I finally downloaded free app for android 'AirDroid' for my Galaxy S, which uses the wireless network. Needless to say there, the flow rates are fastest, sending or receiving only dependent on the quality of your Wifi, and the app uses a browser page: ergonomic, simple and more aesthetic.
