Query: Great gadget!!

I bought the bluetooth due to the hands-free driving requirements in Florida - but - I use it all the time. It works well while I drive (1 hour commute) but I also use it at home while I am cooking, cleaning, etc. The battery holds a very good charge but it is difficult to tell when it is dying (the only bad aspect). It is very comfortable and lightweight, and works great with the Razr.
