Amazing!
My periods have made it unbearable to get out of bed but with my livia I can tolerate the pain of my cramps and lower back ti do a normal days activities. The charge lasts 10-11 hours the pads are good for more than one use. I just wish that more than 3 packs of pads were available at a time due to the length of my pain/period. I purchased for a friend and myself and we call this our miracle machine.
