I have been personally and professionally (therapy, retreats, and workshops) using binaural beats for 25+ years. I have a couple of comments. 
1. I find it so refreshing how you promote without over-hyping. There are so many false and misleading claims regarding this method that it compromises its actual value and benefit. 
2. Personally, your nap recordings have an amazing refreshing and clearing effect on my mid afternoon slump. I have not yet found one that has such a wonderful benefit. 
Thank you, and keep up your great offerings!

Excellent, thank you for sharing, kind sir!
