My father purchased AmpliEar and was not pleased with the product as it did not help his hearing. The product was returned within the 30 day requirement, as advertised. This was back in March. He is still trying to get his refund back. I have numerous emails from this company promising his refund but they still haven't sent it. BEWARE of this FLY BY NIGHT company! If you call them and ask for their accounting department they will tell you that no one is available at that time, they are nothing but a scheming company and have been reported to the BBB and newspapers throughout Florida for their false advertising.
