I bought these when my new Samsung Galaxy started driving me nuts with fingerprint marks everywhere and constant cleaning. My pack of 5 hasn't lasted long as my kids and friends have helped themselves as they loved them so much. They are great, they fit perfectly into the earpiece hole of the iPhone 3GS, iPhone 4S, iPad and Samsung Galaxy with no issues at all. They have stayed on in pockets and bags. I'm about to order another set as these have gone down a treat so are a great stocking filler idea for Christmas too.
