I got this filter and was nervous about putting it on my computer because I usually mess it up in some way. I watched the instruction video they have and the filter went on so perfectly that I cannot even tell it's there, other than the fact that my eyes aren't bothering me! It is so smooth and bubble-free that I thought I might have actually peeled it off along with the top layer as I finished the installation, but I can see a spot at the bottom where I trimmed it a little. I through it was slightly large for my screen, but it fits MUCH better than any other one I have bought! It was great being able to just order according to the make and model of my computer. Much easier than measuring and finding that I somehow measured the wrong way! I don't anticipate ever needing to replace this filter, but if I do I will definitely order this brand again!
