A 2-year-old daughter accidentally head-butted her mammy in the face. The bridge of mammy's nose was red and swollen. I gave her the miHealth set on Acute Balance to use off body for only 2 minutes, followed by Chill for 2 minutes. All redness and swelling immediately disappeared and mammy felt no pain. There was no bruising to follow. It had looked very much like mammy was definitely going to have black eyes. It simply didn't happen - it was instant and very impressive.
