I can't believe I waited years to buy this... best purchase of 21st century so far.
The very first time I placed this under my head, I fell into a deep sleep and my whole body relaxed in a way that was transformative.  I use it almost every day now for 10 - 20 minutes and it has helped with chronic neck tension, tension headaches, low back tightness, repetitive use shoulder pain, mental stress and stuck energy.  It is a great meditation helper as well - I use it while listening to guided meditations and I go much deeper with my entire body because the still point reaction is so powerful.  I feel more receptive and supple from using it.  It has an immediate calming effect after a hard day or a spat or a horrific headline.  It's like hitting "Pause" but where pause means gently working through whatever triggered me, with compassion and stillness.
