I purchase this like a solution to "I didn't answer because I was driving"... then, searching for simple, easy to use and cheap solution, I found this item, and 2 weeks later I don't have any problem with it.- Good sound (if it's placed correctly)- Good mic (clear at the "other side", again if it's placed correctly)- multiple language (I'm chilean... excuse my engrrrish, jaja)- I read many times that this hands free "suddenly shut off"... well, this happens only if you turn off your bluetooth connectivity of your cell, this hands free save energy if no connections are available...- I think that is cheaper than others (maybe the most)Good purchase (some risky [vivo en Chile!] but I satisfied)
