No complaints, just comments. Bought the Dr. Paul SP to replace a seven year old Siemens Touch I managed to lose. This hearing aid is listed for Severe to Profound hearing loss in some places on the web page and also listed as for moderate-severe-profound in other places. My hearing loss is moderate and mostly in the upper range. A common complaint of us older folks. This aid has way more amplification potential than I need but a couple of reasons I purchased it (other than the great price) are the power and frequency range adjustments. For my use I turned the power adjustment to minimum and played with the range adjustment until sounds stopped seeming "tinny." With both "P" range and the power level on the push button at the lowest level, and with the mode on option 2 -- noise reduction -- this aid works well for my use. The usual disclaimer; "Your results may vary." I do suggest turning the "P" adjustment to the lowest level before installing the battery and then adjusting it from there to suit your needs. Taz

I bought these back in the beginning of April, 2020. This was a month after everything started shutting down in March because of the Covid-19 pandemic. My hearing aids that I had at the time started developing major problems after 10 years of usage. Unfortunately I was not able to go to any place to get them fixed or purchase new ones in person as everything was being shut down. So I resorted to online searching for either repairs or new hearing aids. I realized I would be better off buying new aids instead of getting my old ones repaired. I searched for online hearing aid stores and at least a dozen or more places popped up including Hear-Better.com. I immediately eliminated all those stores which were overseas. Then I started looking at the ones left over. Every time I compared all of the stores that were left, I always came back to this one (Hear-Better). I know I needed a hearing aid for profound loss and Hear-Better had a few to choose from. So after much deliberation, I decided to take a leap of faith and ordered two of these aids, mainly because of the price point. And despite the U S Mail was experiencing delays in their deliveries at the time, I still received them within three days after ordering them.
However, after the aids arrived and I was able to get them fitted to my ears, I was more than pleasantly surprised to find I had made a wise choice. They work fine for their intended purpose which is to aid in your hearing. For those who are wondering if they should get these or not, I would say take the leap if you feel comfortable about it. You may be surprised in the results. I'm glad I did and the results exceeded my expectations. But I am going to add this disclaimer; these results are mine. Your results could well be different than mine.
For those of you who are wondering what my hearing loss is, I have a loss of 70 to 80% in my left ear; 40 to 60% in my right ear. I was able to use them right out of the box without further adjustments.

Lost my hearing in 2003. This is the only hearing aid I trust and use! When I was able to hear my footsteps when walking, I was SOLD! Had no idea how much sound I was missing until I invested in these quality, affordable hearing aids.

Bought several different ones to try to find something better that the ones I had... Boy, was I surprised. I could even identify the voice on the TV that I watch every week. These were so bad I ordered 3 more!! I was awestruck about the sound quality of this hearing aid! Wow is all I can say!
