At the same time that I ordered this Ladies Magnetic Bracelet for my wife, I also ordered the Men's Magnetic Bracelet for myself. It wasn't until I received the pair, that I found out that the magnetic version can't be used by people with a pacemaker. That was all my fault, as I evidently didn't read all of the details. My wife doesn't have a pacemaker, but I do. I have a Biventricular Pacemaker w/ICD. I liked the bracelets so much, that I went back and ordered the non-magnetic version for me.
