By appointment only. Good prices on hearing aids and good return policy. You can make adjustment/cleaning appointments at any Costco to correct problems like feedback or volume problems.

Bought them twice, second one because better ones came out.

We are spoiled at our Costco hearing center in Fargo who can usually fix/adjust your hearing aids that day. We stopped at this hearing center but there was just one person working and there was no guarantee they could fix my husbands hearing aids that day.
