I have the Nevro w/remote. The only thing I feel is the battery pack on my back at about waist level. I never notice it until I feel back there for it. The leads themselves are located within the epidural space alongside the spine as I understand it. The SCS is not perfect. I just posted a new discussion suggestion about why the SCS seems to quit. I described my problems there. But overall it has definitely been worth it so far for me. My friend has had her Boston Scientific for at least 5 years and says she probably couldn’t have gotten out of bed by now without it. I have another friend who says even her trial failed so it is mixed bag.
