Amazing best one for me I have ever had the pleasure of trying, the only thing that actually works TOGETHER with my MIND HAVING AUTISM,DISLEXIA, AND DISPRAXIA - & DOES NOT TRIGGER MY ANXIETY. NEARLY EVERY OTHER ONE ETHIER WORKS AGAINST IT OR MAKES MY NERVOUS SYSTEM flare up with a "beat the time , climb up the mountain" aproach instead of a "Great. we will start with this scene, then, we will move to the next. Just flow with me." Aproach. My kind of mind is actually best working in a flow .
