Seems to work okay
I purchased these on a whim. I'm familiar with magnetic therapy as I have used it before for circulation. The rings are uncomfortable and snag on the blankets and pillows at night, but I do seem to be sleeping better. One night I forgot to put them on and I didn't sleep that good that night. I do feel the magnets sometimes when I have them on, kind of like I can feel the magnets working. If the rings were not so bulky and more comfortable I probably would have given them five stars.
