Very good device, Easy to use and set up, fit is comfortable, sound quality is very good, and stand by /talk time are great, I have had a few other bluetooth ear pieces that fit better but sound was poor, longer stand by and talk time, but I figuerd if I was on the phone that long I need to re think my life, when I first purchsed it because of it's size I thought I would loose it, year and a half later my dog chewed it, Great device for the money.
