Good communication, very friendly, I didn't feel like they were taking advantage of my lack of computer skills.

Disappointed
I have been wearing the nano hearing aid that fit behind my ear for about 2 years! I like them. But I thought it would be nice to have the small rechargeable ones. But I don’t think they are worth it!! Followed all instructions but can’t get them to work!! What a waste of money!!😩

The Worst Scam Ever
I was given 2 sets of hearing and neither one game me 1 second of amplified hearing. I am a retired senior citizen who was raised by deaf parents. I have lived with the disadvantages that not being able to hear presents. I have bought many hearing aids during my life time and have spent thousands on them because of losing each and every one of them. I have run into financial difficulty which makes it impossible at this time to purchase those quality hearing aids. I have had to do things like, turning the volume up to maximum. Asking people to repeat things over and over.etc etc. When I received my first set,which I upgraded because I was so excited to be able to hear better I followed the directions and nothing. My heart sank. I read the directions again thinking I had done something wrong. Nothing! I called your company and an agent said she would help me she worked with me for an hour and nothing. She then said we can try something else in the morning. I waited all day and nothing. The next day another agent calls and apologizes and said she is sending me another, better hearing aid. I got excited again and waited for my new hearing aids.When they arrived I thought they wouldn't scam me again. Boy was I wrong, the scam continued.
I am depressed, I feel worthless, and angry that I fell for your scam.
Do you (Nano) get joy from taking advantage of senior citizens? My first thought was hoping bad things happen to you and your families but my faith quickly erased that thought. No one should feel like I feel even those that set out to do harm to others. I will pray for you and yours.

DO NOT buy a set of Nano CIC hearing aids…
Buying a set of Nano CIC hearing aids for $247 on 5/12/2023 with order #570018, I was assured by the Nano Customer Service that if it didn't work, they had an advertised full refund policy if returned prior to 45 days. I tried the aids but they were more like amplifiers than good hearing aids (along with multiple other quality problems), so I requested to send them back on May 19. I received the necessary RMA codes and directions for the return process. I soon received a mailing label with USPS tracking number and shipped them on 5/30, receiving an email on 6/1 that they had been received. I also photographed the products and shipping containers with papers, as many Nano reviewers warned people to do so. However, 13 days later, only after my request for a status update, on 5/13, I received an email that they had denied my refund request due to damage to the product, with a picture so blurry, I can't see the imperfection they claim. Then even after I rejected their product, they tried to sell me another replacement pair for a $79 fee! I wore the hearing aids as provided for only about 2-3 days per their instructions and kept them in their special protective package. Upon packing for shipping back to Nano, they were in the exact same condition as I had received. I have photos of the hearing aids I packed away with the original packing box and papers. Many other reviews & complaints I've read about on Nano show this exact same problem suggesting to me that if they were truly damaged as described, then Nano should review how their refund department handles all these returns. I have learned that Nano seems to look for different ways to deny requested refunds which hurts their reputation as a truthful and helpful company. I am sorry to have to write this complaint in the first place, but I'm simply asking for my refund of $247. Perhaps this will help warn other people about this company. I have learned that this Nano company has an F rating by the BBB, and is not accredited by the BBB. Nano also has a 1-star review rating! Even though they have a CA address they have NO CA business license. The company uses a residential address as it's corporate address but it does not exist. All of this leads me to say BEWARE of NANO!
