Query: Useless

I bought this based on all the positive reviews. The sound quality of the speaker is excellent. The problem is the people I talk to can't hear me. They all say it has a lot of bacground noise, and I have a quiet vehicle. They also say it breaks up a lot so I have to tuen it off to talk to them. I might have been better off burning the 35.00 for this, at least I would have felt some warmth.
