@prbiruk, I think you are referring to the RST SANEXAS. They have one of those miracle fix videos - https://www.youtube.com/watch which is a warning sign to me but it is just my opinion. I tried a tens unit that was very expensive and it did not help me at all. This seems to be another style of tens that will "repair" the nerves by electrical stimulation which is another warning sign for me.

I'm just not liking their too good to be true story but that's just me and my personal opinion. Good luck if you try it and I really hope it works for you. Hopefully some members who have tried it can share their experience.
