I am asking because I was issued one as an emergency backup for a student in my class. I have, to my embarrassment, lost it. I have zero idea how much a small magnet device like this costs.
ESutures.com wants $99 for the bracelet (magnet model 220),but that may be the inflated price they charge insurance.
I see personalized VNS magnet bracelets going for around $25 on eBay and Etsy.com. At that price I think it’s just the bracelet onto which one attaches one’s own magnet.
Is there any reason why a $5 magnet from a hardware store won’t work? Is there something special about another kind of magnet? Is there another kind of magnetic field? Is there any difference between magnets other than strength?
