Simple, yet extremely effective
Having lower back and glute problems, when I saw the Backballer advertised, after reading some reviews, I took the plunge and ordered one. Its had an instant effect. My lower back pains are about 10% of what they were previously, and my legs are getting better and better each time I use it. I use it 4 or 5 times a week for about 5-10 mins, I have it under the sofa in the sitting room, and use it whilst watching tv. I would definitely recommend this.
