Bests & Worsts Reviews from Amazon

The massager folds in half for easy storage, comes with user manual. Has a elastic velcro back strap for kitchen/dining chair, works great in a recliner or couch, the adjustable height is simply the height at which you place the back portion to fit your body. Side pocket to store remote in. Once plugged in, Power button to turn it on, demo does all of the functions. Intensity is the speed at which the balls move does not change the pressure applied. When heat is on the balls light up. Full back function goes from shoulders to hips, low back stays below waist and upper is mid back and shoulders. Push the Spot control when the massager balls get on a spot that you want focus on and the balls stay in that spot. Vibrate function is only for the seat cushion. The overall function of the massager is strong, such that it could cause you to feel tender. As stated in the manual, I recommend that if your build is thin to use a towel or foam padding under the leather cover to decrease the pressure it applies. I would recommend this product.
