As many other reviewers have said, be sure you want to know before you buy this or any other product. Does what it says. Can pick up sound through noisy wind, traffic, etc. My only complaint is that there is no indicator to tell you when it’s fully charged or maybe a clear indicator. It would be nice for there to be something that could show you when it’s plugged in to the computer. The flashing lights are very confusing. When it goes dead, you have to reset the time and date.
