It worked for me
I am one of the ones who can give this a 5-star review.  It either gets a 5-star review or a one-star review.  In other words, it works for some and not for others.  I don't know how it works, but it does.  Someone in a scam review said the adhesive was smelly.  I do not know where they get that.  The only thing I have trouble with is separating the vinyl covering over the adhesive so that it sticks on both sides, but it is not impossible. The other day I went to the doctor's office and removed my patch.  I forgot about it.  That night I noticed that my back was hurting and then I remembered that I had removed it so I retrieved it and put it back on and problem solved. So if for some reason I am a victim of a scam I have not realized it:)
