Review (1/5): False Advertising. Don't be deceived as I was.
Product image clearly says "48 HR" protection. With shipping I paid about $14 for this item. In retail store this 24 HR version costs about $6. The only 48 hour versions of this product DO contain Aluminum. This was very disappointing.
Update: I contacted the seller and they reimbursed me half of the value of the product which is fair. They still haven't changed the product image though.
