Not worth it
I felt this product is absurdly overpriced. I like the awareness the product is bringing to attention to breathing overall but I tried it for a week and noticed nothing special. If you are going to put time and energy into something so tedious, you should experience something special in a week's time. That's my experience with supplements and health things in the past. Even with exercise you feel good after the first time. So I just don't feel the combo of the price and practice is worth it.
