I always advocate people who are going to be talking on their cell phones all the time while driving to use a bluetooth headset because in my opinion, their is a higher risk of being involved in an accident from not using a hands free device. Plus, it works up to 30-33 feet away and today, the user can now listen to music and answer his or her call within a click of a button. Plus, if you are doing grocery shopping, you don't have to take out your cell phone, but rather keeps your eyes on your groceries and your hands on the cart, lol
