For those who say they see no results after a month of use, if you use the seat belt and you do not cardio next to burn fat, it's normal, it's like do just bottomed abs indoors every week, if not cardio beside it certainly muscled abs but this little layer of fat above will not leave. So cardio belt + (run or bike or bike elyptique at least 45 minutes) and the results will be more than visible!
