I purchased ReSound Quattro 9 hearing aids from HearSource.com. Their staff was friendly and professional, not pushy. I received my hearing aids on the 4th business day after I ordered them via UPS. They were preprogrammed for my hearing loss. The fine tuning and adjustments was accomplished as soon as I requested that particular service. I Will recommend HearSource.com very much. I saved $2,400 compared to my local hearing aid office for the exact same product.
