Over all our products are superior to the many i have tried. So far, I have only tried the duo one time so I cannot make a fair assessment. I can say each item individually in the duo pack works exceptional well to induce calmness and sleep.
Consistently great and shipping is consistently great
Easy calming high that acts like a saliva without any paranoia.
These are very helpful for people with ADD. I take half of one to supplement my prescribed medication.
