This Review Title is Waist of money and the content is: Please, don’t waist your money on this, they do not work as advertised. It is so dry that the magnet didn't work, contacted the customer service, they said you cannot get your money back, ordered another product from them and receive another crapy product. They were old and not functional.There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
