My husband got these for me as a gift a few years ago. I can't wear them for long periods of time but I try to put them on once a day for a few minutes. The buttons are oretty hard and it's a very intense sensation.

I can't say that they work the way a reflexologist would but they do feel good. If I just stand and slowly sway back and forth I get chills all the way up into my scalp- good stuff.
