Query: Taking it back

I bought this yesterday and it's going back. For me, it only works properly about half the time. I made one call, it was crystal clear, the next call, I was told I sounded like I was in outer space. Too unreliable for me. The only pros were I like the color and it fit well. I bought the Motorola H670 and have had no problems with it.
