    • Love this product for focus and brain health!
Review Image by Kristie Carter Health & Wellness
I use this product daily as part of my wellness routine. I use it for approximately one hour every morning as I do my Bible study. The gamma frequency helps me focus on what I am reading and I feel I have better retention as well. I bought this device after doing many years of research in to frequency and light energy. I have suggested this product for many friends/family that have memory and cognitive decline issues. Wonderful product! ... show more

    • Too early (by three decades,) to tell if it works or not. But trying anyway.
I don't know. Does it work? Does it not work? Better safe than sorry? My family member is in some middle state of dementia. it's been awful. Really horrible. It has made my entire family wonder when our turn will come as it appears to run in the family, and we've taken FAR worse care of ourselves than the person who has this life altering condition at present. So this sent me on a journey of either truth or quackery. Does this work to stave off the things that cause cognitive decline? I don't know. It has made me dream really well, which is kinda fun? But then ya read that people who do not remember their dreams do not have as much of a problem with cognitive decline. So is the brain taking a mental walk prematurely when one dreams? Again---I do not know. It does flicker, and I can only sit near it about half an hour before my eyes start bugging me. It is bright, but not annoyingly so. But does it work? Check me in another 20 years Amazon. Has my cheese slid off my cracker? Or am I someplace better because of this device. I am sleeping a tad better? So who knows. But it can't hurt, right? ... show more

    • Works
I've noticed a marked improvement in my mom since using this. I put it in her family room as she spends 99.9 percent of her time in there. I told her it was to kill bacteria so she didn't get sick -that she must leave it alone and not touch it ---and most importantly I PUT IT ON A TIMER. It kicks on every morning at 10 and off every night at 10. She literally sounds more like her old self when you talk to her now. We've seen improvements in her short term memory as well. Prior to she would call numerous times a day and not remember calling, this has stopped as of 2 wks ago and if she does call, she now recalls previous conversations. (we've been using it 4 wks to date) I'm not expecting miracles, but even these little improvements we are so thankful for. ... show more

    • Great lamp except that it does not meet my standard for durability
I like this lamp — it supports my processing and mood by reducing brain fog. Yeah, I like it a lot. However, after purchasing it 14 months ago — and using as directed on approx 85% of mornings — it has already burned out.

    • Game changer!
I’m a 76 year old female and have begun to be concerned about my short term memory. I have also not been able to sleep more than 3-4 hours a night lately, even after taking a sleeping pill. After the very first time using this light for one hour, I slept for 8 hours straight. I’ve been using the light now for 3 weeks and have stopped taking sleeping pills. I fall asleep easily and, even when I do wake up in the middle of the night, I am able to go back to sleep quickly instead of staying awake for 2-4 hours. It has been a game changer for me. Hopefully it will work for you too. ... show more

    • Aw, Sweet Sleep!
I am so impressed with this light. My husband with AD was getting up every hour during the night. After the very first day of using this light, he started sleeping through the night. Two nights ago he slept 9 hours straight! The only change in our routing is this light!! We have now used it for five nights and both of us are getting more sleep. The first time we tried to use it, he tried to block the flickering light with his hand. I explained to him that he should not stare at it, but let it hit his peripheral vision. I started having him do WORD searches with me during the hour we use this and he is fine. He doesn't even notice the flickering. I am waiting to see if memory improves. Even if it doesn't, this light is a game changer for us! ... show more

    • Lightbulb included, do not need to buy separately, misleading.
Still not sure if the lamp is working, will continue to review. You dont need to buy the light bulb separately, its already in the lamp, ad misleading that you needed to buy the lightbulb, wasted money on the lightbulb.

    • the jury is still out on effectiveness
I bought this Aug 22, close to 2 months ago. No perceived change or improvement, but I'm not giving up yet, hence 2 stars. The jury is still out on this. I've been running it for about an hr a day, about 2 feet ahead and slightly to the side, so it's always in my vision. I have not yet added the 40Hz sound. Will report back if the 2 together make a noticable difference. I've always had irregular sleep patterns, one drug causes a night or 2 of insomnia, and I frequently get up every 2 hours. But one slight change is I'm not getting up as often lately (about twice every 4 hrs, vs 4 times every 2 hrs) Dunno if this played a role in that or not. ... show more
