The infinity wristbands and similar competitor products are a scam. Some countries have banned their sale and all of their marketing because everything they claim that the products do, is totally unfounded. Other countries have forced them to change their marketing claims. Some stores in the UK have refused to stock the products or have to take them off the shelves because the makers cannot produce any evidence whatsoever to substantiate their outlandish and crazy claims.

If it sounds too good to be true then you can be pretty sure it is.
