I’ve had the device for two weeks now and I have noticed improvement in so many areas! I bought it to treat chronic fatigue and brain fog, and I have noticed a big difference in the brain fog. I haven’t had the feeling of “cotton stuffed in my brain” in a week and a half! That is amazing! I’m sleeping better, the popping in my knees has disappeared, my energy levels have started to slowly increase, and a surprising benefit I didn’t expect was that my cellulite is significantly less noticeable! All this in only two weeks. I’m looking forward to seeing the full benefits I get once I’ve used the device for a few months. I’m very happy with the red light panel I purchased! The only bummer is that the hook that goes on the door is too small to fit on the doors in my house. Maybe those need to be made a little bigger.
