I had my first full-body massage on a cruise this year and this brush was used during my massage. When I first felt it, the tingling sensation was so wonderful, I said "Oh wow, what is THAT?!" and, LOL, I bought one from the therapist right after my massage. It was an easy sell, and I have been using it every day since and LOVE it! My skin feels so much smoother, and it has definitely improved my circulation and overall feeling of well-being. I plan to purchase it as a birthday gift for all the women in my life that I care about so that they too can enjoy the benefit of this wonderful skin brush as well.
