I just teceived mine BT03 a few days ago. Total cost 60 USD (shipment to Greece).
I am using it with my Dell Streak 5. Sound quality is not so good if you are not using the handsfree earphones. Bluetooth: very easy to pair and to connect, also is stays connected and you can continue talking in a distance of approx. 7-8 meters, Streak in one room and the headset to another, in my house. Battery looks good till now. The music/mp3 button also does not work for me. Synced all of my contacts but they are sorted probably in the Chinese alphabet !!! A bit useless . In general a very good bluetooth headset with the keypad to be the best thing !
