I use an iPen with my iPad and I could hear it sometimes make a scratching noise on my screen so I was worry about it damaging the surface. I purchased this 2 pack of screen protectors and they work great. They feel like I am writing on paper instead of a screen. My 7 year old daughter likes to use my iPad to draw and now I don't worry about her scratching my screen when she uses the pen and it is easier to do the finer details of her drawings.
