It's like a wearable hug for nervous system, using touch therapy. gentle, soothing vibrations that train your nervous system to recover and rebalance after stress. You can use it for energy and wake up, which is a kaffin free way to get energize. The first time i tried it, i went so much deeper, deeper than i had been in years. I put on rebuild and recover, and helped me wind down what used to be like a cocktalor or a desire for something else.
