Not sure about it...
I'm honestly not sure if it's helping or not. Sometimes when I am having trouble sleeping, I lay my palms on it flat and it seems to relax me. But we're going through a quite stressful time, so I don't know if it is just too much stress to help or if it's helping and everything would be a lot worse without it! One thing I don't like about it is it bunches up. The straps just don't keep it in place. I think these are where it was folded in the package, so I'll try washing it.
In a weird way, even though I don't have any real feel for whether it's helping or not, I'm glad I bought it. We are grounding it outside with an extension cord.
