Review on Rechargeable Digital Hearing Amplifier: Banglijian, Noise Cancelling For Adults & Seniors, Latest Upgrade by Michael Kosack

Amplifier significantly improved hearing sounds in the ear with the greatest loss. The unit is generally comfortable and unobtrusive. While I don't know how my improved hearing would compare with a custom hearing aid, I am very satisfied with the results for the significantly lower investment. My only criticism is the distorted and disturbing sound produced when pieces of metals or other objects are jangled together (e.g. a set of dog tags, or keys on a key ring). It results in a sharp clashing sound thru the amplifier.I am especially impressed by the company's customer service. After about a month of using the device, it seemed to stop working. Despite being fully charged it was not amplifying any sounds nor could I verify that it was actually turning and staying on when I pushed the power button. Within 1 day of sending the seller an email via Ebay concerning either a refund or return of the unit I received the seller's response offering a free replacement. However, the seller recommended that I follow its instructions to test whether the unit was actually amplifying sound (even if it wasn't being heard), and then to clean the ear piece which might have been causing the sound blockage. After completing the testing and cleaning the unit was fully working.
