Although I approached Modius somewhat doubtfully at the behest of my wife, I must say that the results have been remarkable. At first we did not lose pounds but rather our fat started to melt away - to our surprise, our double chins and tummies have disappeared. We have gone "lean"! Not only have I lost weight effortlessly, but I sleep better and have more energy - I now virtually sprint up and down the stairs in our three-story house. We have recommended Modius to our family and friends, and purchased an additional Modius so we each have our own headset now.
