I ordered this headset for my wife.  However, I have used the same model for over 1 year.  I rate it as an excellent little gadget.  I use my cell/mobile phone as my only phone (no land line).  However, my arms get uncomfortable and numb after holding the phone in talking position for even short periods of time (Ulnar nerve compression).  Using this earpiece, I do not have to worry about my arm getting numb.  Better yet, I have my arms free for safer driving, carrying groceries, typing, cooking, etc.
