Customer reviews for the Original NeutronicEar product have been generally positive on the NeutronicEar company website. However, consumers should be careful with this product because the reviews may represent the views of the company and not be reliable.
Customers who reviewed the Original NeutronicEar on the company website said that they were pleased with the product's battery life, sound amplification, sound quality and the company's service. One customer did report hearing some interference but was otherwise happy with the product. However, in 2009, when NeutronicEar was called Crystal Ear, the FDA sent a warning letter to the company because it failed to meet guidelines for producing a device that could mitigate impaired hearing, as the agency reports.
