    • Very convenient--and exactly as advertised
Sleek, compact and easy-to-use digital playback device. Comes with pocket-size hardshell carrying case. Hit the play button and you'll hear a brief voice announcement followed by one hour of the tone. Then it stops. There are also buttons for "back to the beginning" and "jump to the end". Holding the play button down shuts off the unit. 40Hz buzz tone sounds the same a the one posted on Youtube as "Exact 40 Hz Gamma Brainwave audio used by MIT" study. Recharging off a laptop USB port (cable included) is easy and just takes a few minutes to charge. Charging cable plugs into the earphone jack on the unit, keeping it small and simple. Ear buds are good quality, but don't come with alternate size ear pieces, and may be too large for some people. Note that, contrary to the instructions, ear buds are interchangeable--there is no Left ear or Right ear shape. All in all, a very nice design, well-made. ... show more

    • Waste of money
I got this for my mom who has Alzheimer's and it did absolutely nothing for her nor me nor anyone else who saw the flickering light or had on the annoying headsets. This does NOT work! Don't waste your money. They should be shut down for selling foolishness like this to people who hope something alternative will work. ... show more

    • I Can Remember My Dreams Again
My dream life has always been really important to me, but lately I have been unable to remember them. I almost could but as soon as I opened my eyes, all trace recollections of the dream would vanish. Since I started using this device, I have been recalling dreams just like I used to. I'm back to having a rich and vivid dream life. When the session is over, I hear an odd sustained harmonic tone for awhile which eventually subsides. It makes me wonder if my neurons are also continuing to oscillate. The only thing I really hate about this device is the loud voice that comes on at the end just to say that the session has ended. It startles me so badly that it hurts. I'm sticking with it, though. I am loving having my dreams back. I think I'll buy one for my Mom. ... show more

    • They just don't last
I've purchased many of these over the years. A radio article about 40Hz research sold me to the idea that we can improve our brain's ability to clean itself. This sound has been shown to do just that. However, the quality is poor. I've never had one last for more than a few months. Some stop working almost immediately. Great product. Poor quality. ... show more

    • Died in 2 weeks
I used this Gamma Clarity 40Hz Audio device one hour a day from April 20 to May 3, 2023. Charged it between uses as the instructions said to do. I handled it very gently. Today it was dead as a doornail. Won't turn on, won't charge. I even tried different chargers and different outlets. It was very nice while it lasted. The earbuds were too large so I used a set of Skull Candy earbuds that fit me better. It's still dead with the original earbuds. The instructions require a magnifying glass to read. There are other reviews complaining about short life so if you decide to get it, hold on to the packaging because you might need to return it. ... show more

    • Missing charging cord
The unit arrived on time but was missing the charging cable. I do not have one with a headphone tip and USB at the other end to charge the unit. I put in a request to the seller for the charging cable. I hope it comes quickly so that I can charge and use it soon.

    • Worked for 3 uses
On the 3rd use it quit working. Only comes on for a split second and goes off. Disappointing product

    • My Family Has Had Few People With Signs of Alzheimer...Buy Why Take Chances?
Over the past two years, I've been watching TedTalks and keeping up on the ongoing research. I read the book. "The End of Alzheimer's" by Doctor Dale E. Bredesen, MD. While I think my odds of getting it are pretty slim, I wanted to do everything possible to reduce the probabilities. One of the more promising protocols comes from Gamma Clarity 4hz Light Build. Their devices are inexpensive, and they are pretty much based on early research. But one downer is that while the initial conclusions seemed hopeful, there has been a lull in activity to get the research going. I hope they get their act together. ... show more
