I’ve been thoroughly impressed and happy with the lights I’ve gotten so far. The whole family partakes in “red light time”. Most notably: My son (3yo) was starting to show some really disruptive and legit OCD issues on an increasing basis (2-3 meltdowns from what I would describe as ‘word sequencing rewinds’ that he would need us to do to calm his anxiety). I was hoping that this light therapy would help and boy have I (and the whole family) been happy with the results. He has completely stopped with the OCD disruptions and has a much healthier sleeping pattern. We do two 20 minute sessions a day together (just playing games in front of the light). My skin health has improved quite dramatically and I personally feel like my morning 20 min session is better than any cup of coffee. Would recommend! I’ll probably be buying another set and am looking to make permanent furniture to lay under.
