Query: Poor use of funds...

That is what I would call it from a business standpoint. It stopped working for me within about 2 months and when I called the company to complain and they informed me that they would not replace it unless I had my receipt and when I told them I didn't keep my receipt the young women told me to give her the "date-code" on the headset and when I gave that to her she told me that it didn't compute. So therefore I would have to pay to replace it. I think that any "decent" company would have taken care of a customer in order to keep them happy. I would recommend something besides Plantronics. Good luck and God Bless.
