I have used it for only about 1 week with a Razr Phone, connects easy works well ,, the only thing I did not think of is Phone battery life while using bluetooth ,, they seem to go fast , but no problem so far ,I do wish the range was better , but you learn how far you can go from your phone ,the voice pick up is very good as I tend to talk low and my friends still here me fine even in my old loud VW,, so if your looking for a good head set for you razr and you on a budget like me ,, this one is great ,
