I got the silver stainless steel one. It was delivered on September 15.
I wore it everyday. I didn’t take it off because I thought the magnets needed to stay on your skin.
Anyway it was a little over a week when I noticed my wrist looked dirty under the bracelet. I took it off and saw that the “stainless steel” had worn off on the underside and the copper was exposed.
Stay away from this one.
