Review on Telephone Microphone Cancelling KX TGF380M Grandstream by Mary Williams

This headset has great sound. One problem - there is no information about the company that makes this product. There is a small guarantee label in the packaging. There is no place for any information, no serial numbers other than the part number. Although you can get warranty information on a form, there is no place to send it and no contact information. The packaging says it was made in China. That's all. At least the headset works perfectly. Without the missing information we would have given 5 stars.
