This is a good inexpensive wireless bluetooth headset. Small,lightweight,easy to use. Range is good up to about 30 feet. The faults battery doesn't last very long as it should, and unit will quietly go off after a period of time without your knowledge. So if your between calls or waiting for call it may go off and you cannot answer without reconnecting with phone. Then of course you missed your call. That's the biggest disappointment with headset.
