It's no bigger than my AARP membership card. It costs less than $100 and there's no contract. Once I connect to the bluetooth device in my ear I don't need to look at it again until I turn it off and put it on a charger.
Now, here's the interesting part. It's a phone and does what it's designed to do; send and receive calls (texts too if you're into that). It's got a few extras like a calendar, contact directory, time of day, and a microphone. If I wanted to I could use it to play music, but then it would start being a smart phone and I like mine just plain dumb.
