I've had mine for about 8 months. I saw some relief within a week of getting it. And to the people that have it in their foot/leg; put two electrodes behind your knee (one above the other) and two where your leg and hip meet (same way). This way, they're over the major artery in our legs and that will help stimulate the blood flow. I know it's uncomfortable because our legs are so sensitive, but it should eventually help.

Love &hugs.
