Query: Frustrating

The only reason I gave it two stars was because it actually did free my hands to drive, as I have a standard transmission. The sound does not go high enough, and often the people I was talking to had trouble hearing me.After the first week or two, it would start automatically switching itself off, after and sometimes during a call. And it would lose interface with my handset very often throughout the day, especially while trying to place calls. This created an almost maddening experience.I will definately look elsewhere for my next one.
