Unfortunately I have not been able to use the hearing aids regularly. I am using the smallest bulb in my right ear and it is uncomfortable and hurts when inserted. In addition, the charge only lasts a few hours. They are hard to adjust and the screeching noise is terrible. This has been a problem since I purchased them.

The Good and the Bad
2 1/2 STARS IS ABOUT RIGHT. For me, wearing the Nano Hearing Aids is a mixed bag. I was able to wear them all day the first day, and although I could surely feel them in my ears, they didn't bother me too much at all. Several months later, I can still wear them all day, and feel them, without much bother; i.e. it was better than expected at first, but I never really became used to them being in my ears to the point that I don't notice them.
If that were the only issue, I would give them at least four stars, but unfortunately, there are other bigger issues. In a nutshell, they work really well to amplify loud sounds that need little to no amplification, but not as well with lower or softer sounds that do need it. For example, in church, when a baby half way across the chapel screams it about blows my head off, yet I often have trouble hearing someone right next to me if they have a softer voice. I have been tempted on several occasions to say "just a minute, let me take my hearing aids out so I can hear you".
Another issue is when driving with the window down, or being outside with even a light breeze, they make a frequent popping sound.
Also, hearing myself talk doesn't sound the same at all when I am wearing the Nano Hearing Aids. It does not feel natural to talk with them in.
Finally, I have noticed that often I can hear loud enough with them, but I still have some trouble understanding what someone has said; i.e. I don't believe the increased sound is quite as good as if I were naturally hearing at the same volume.
For someone with quite poor hearing, I suspect they would benefit more from the Nanos than someone with less hearing loss. For me, I haven't decided for sure if they are better than nothing, giving the stated limitations, though I'm sure they are a blessing to other people, especially considering the low price.
For the price, I'm sure they are well worth it for many people. For me, even though I have had them for a few months, the jury is still out.
One side note: I started out with the basic Nanos, and after a few weeks I upgraded to the next level which are the digitals. The digitals did do away with the frequent squealing sound from one of my hearing aids, (which may have been more about the domes) but otherwise I didn't really notice a difference.

They were worse than no hearing aids
They were worse than no hearing aids. It was a fight to get an RMA. I have upcoming treatment for brain cancer and needed to get this done, so frustrating. But the RMA was finally given, and they should arrive in LV today.
