Supertooth II - An expensive gizmo
This sun-visor mounted bluetooth speakerphone is not a new technology. This bluetooth gizmo dubbed Supertooth II is meanth to 'pair' with your bluetooth enabled phone to give you complete handsfree duplex speaking plesure while you drive. It comes with a rechargable lithium ion battery that is claimed to give you 20hrs talk time and 800hrs of standby time. US$129.99. There are competing models that could be found cheaper and I feel for that much money they could have designed some sexy curves on this thing. Although a very useful tool for many who spend a lot of hours in their car, I would recommend buying this if or when the price drop to under $100.
