This device is incredible. It's a slow but very effective burn, and you need to use it consistently over time to get the benefit of it, but the benefit is well worth the wait. I'm 49, female, caucasian, and peri-menopausal. My weight has been creeping up over the last few years, as my hormones change and cause my body to hang on to fat. In the last three months of 2017 menopausal symptoms really kicked in, and my weight shot up about 10lbs (5kgs.) I came into 2018 on the cusp of being medically overweight, which is not a good place to be either health-wise, or for the sake of your self-esteem. Usually women of my age find it impossible to lose weight, but not with modius. I have used it pretty much every day for 9 months, and from a starting point of 68.5kgs/151lb I am now 62.5kg/137lb and the numbers are still going down. My ideal weight is 60-61kgs, and it is now within my reach, thanks to Modius. My BMI is in the middle of the normal range, my body fat is going down, and I am back to a dress size that makes me happy. (I have also been doing intermittent fasting, which helps, but Modius did the lions share of the work for my weight and fat loss journey.) Massive thanks to all at Neurovalens for creating this device. You have changed my life.
