I've worn hearing aids for 20 years...I have 2 Phonak Audeo P90 Rechargeable hearing aids. "Hearing Well Matters" in Burlington Ontario set them up. Rob Hamilton does wonderful work. I wear them about 17 hours every day. Rechargeable Batteries barely had enough capacity. Phonak has been excellent. They replaced those hearing aids and my charger with new equipment. Thanks Phonak! Thank you "Hearing Well Matters!" Rob you do incredible work.
