This is the 3rd pair of hearing aids I have had over the last 12 years and the best yet!. Mike is very knowledgeable about products and takes the time to assess individual patient needs to ensure that you have hearing aids that work for you! he is not only more affordable than some larger companies but he proves excellent one on one service! He is honest and trustworthy. The Cellion hearing aids I got three weeks ago are the latest technology and are such high quality. I am thrilled with them!
