My husband was finally told he needed hearing aids. The ones our HMO "suggested" he get were $4,000 to $8,000. They would not pay for the hearing aids as it was not part of our coverage. We did a lot of research for a better price. The best price for the best product was COSTCO. The hearing specialist were wonderful. Top of the line was $1,999.99. My husband is extremely pleased with how they work. He has the option of batteries or they also gave him a charger. When he takes them off at night he just puts them in the charger and they are ready for the next day.
