Pros: portability, plays bluetooth streamed music over my car FM stereo almost as clear as XM. It's incredible with my phone and voice recognition. Others always hear me, I'm able to have hands free in any car. Battery life can be over a month based on usage

Cons: nothing

Overall Review: For around $50 there is no reason everyone with a bluetooth phone shouldn't be using this. Take the phjone away from your head while driving and buy this...
