This massager is life-changing. Without a doubt, one of my favorite things in my life right now, and it’s portable and light so you can bring it with you on the go. After gardening for three weekends straight, the knots in my back became so tight I woke up with tingling hands each morning. After seeing a chiropractor, he told me that consistent massaging was the best way to keep knots like this from recurring. And woah, was he right. Joe and I practically wrestle over who gets to use this wild device while watching T.V. and both of us have found it useful for everything from sore muscles after a workout to persistent knots, like the ones I’m getting in my upper back.
