Just had it implanted in July but I am experiencing significant relief in my feet, legs and somewhat in my lower back. It is definitely something you will have to get used to but well worth it so far. My only true complaint is that it doesn't even touch my hip pain and the area where they implanted the unit is still sensitive to the touch. Also, you can feel the unit through my skin, it is a pretty significant lump. And I am not a small person, there is plenty of meat to cover it. lol Well, and I also constantly lose my remote. lol
