The light works great. I like the flexibility of choosing different settings for the red, NIR, and blue lights. I wasn’t able to get it to work with the app; I use the voice commands. It doesn’t come with a dust cover. My primary concern with using the larger panel is that it’s more difficult to isolate the treatment area. There’s not a lot of research available on how red light therapy affects people with bipolar disorder and ADHD. Be aware that treatments of as few as 3 minutes may be felt in your head (especially when treated on the front). If you’re sensitive to your environment or to your body’s immune response you may want to take it slow and support yourself with extra rest and hydration.
