Summary: The bluetooth works fine and the battery charge lasts long enough. As long as you are within 8-10 feet of the phone (no walls or disturbances) it works fine. For regular conversation with your family it is fine but recommend not using this bluetooth if you are making an important call.
Pros: The bluetooth is cheap and works well
Cons: The sound quality is not good. Almost all the time it is hard to understand when the person is using this bluetooth on the other end.
