I have had the very expensive hearing aids in the past. My hearing loss is anywhere from mild to moderate. I decided to try the Lexi hearing aids due to the Bose technology and I am very happy with the result. While it doesn't have all the bells and whistles of the more expensive hearing aids. It does have what I need, the ability to hear when people are talking to me or on the television. The bells and whistles are not worth another $3,000 to me, so these hearing aids work beautifully and in the way I need them to work.
