A great produce all the way around! I use it both by reading the descriptions and pick what is most supportive for me at the time. It's also fun to just intuitively listen to the different frequencies, go with the one I'm liking the most at the time, then read what it is supportive of. Super lovely... Soothing, calming, and has supported deeper, staying asleep at night, And peace and calm during the day - Thank you!
