My husband and I use both Mini Magic and Big Magic. He had a traumatic brain injury (TBI) over Three years ago. The big magic stays on all the time and mostly on his side under his head. I noticed he’s quieter at night when he sleeps with the big magic. My husband makes a lot of noise (talking and moaning) and has more bodily movements if he doesn’t sleep with Big Magic. The mini magic helps both of us with pain. We just strap it on or put a bandanna around it on our necks, or in our waistband for back pain and forget about it. Two useful tools in our healing arsenal of tools.
