That's a great idea, but they only last a few days on my iPad and iPhone, after which the foil falls off and is lost rendering the product unusable. This happened with six individual packages of the product. There is a stainless steel option, I will try that now. UPDATE: Turns out they're just as bad. Don't waste money. I have them on my laptop and so far so good.
