The most common complaints against Neutronic Ear are that the product does not work and the company is slow to provide promised refunds, according to the Better Business Bureau's website. The frequency of these infractions has led the BBB to give the company an F rating, as of July 2015.
Furthermore, it is likely that the Neutronic Ear is the same product that was once marketed as the Crystal Ear. Both products are based in the same location and use identical pictures in marketing materials. The Crystal Ear violated the Federal Food and Drug Administration's guidelines in failing to properly identify and test a product that falls under the category of "medical device," fraudulently claiming to be a hearing aid. The product is a sound amplification device, not a true hearing aid.
