I haven't used these screen protectors for screens of any electronic devices so I can't review how it performs on phones, iPods, camera diplays, etc.  However, I can say that these are awesome for putting those city stickers or parking stickers on your windshield that need to be replaced annually.  Using these Fellowes screen protectors has made it less of a hassle to remove and replace those pesky stickers year after year.  It applies cleanly to your car windshield and removes harmlessly in one piece with a box cutter edge.  No more having to use a blade to scratch away the stickers pieces at a time as it breaks apart.
