The positive effect of the bracelet I've noticed after regular wear about my joint pain; this would be 5 Bewrtungspunkte. Even in reviews watched rust symptoms in the magnet can not be seen, but I do not sweat, even in sports activities excessively. The metal fastener is however not at high load broken after three weeks, so I have to make do with Isoliernand what works, but can not be a matter. A maximum of 1 point. Therefore my judgment result with 3 points
