Installation is fairly easy. Clean the screen, attach the protective film. What makes it a little less than 5 stars for me is that it's a bit difficult to align just right. I thought I lined it up perfectly and when I was done there was a bubble near one of the corners that I just couldn't make out. It turned out to be slightly off center and I think that's the difference. It's a fixed-size bubble, but it's close enough to the edge that it doesn't obscure the actual screen. I think I'll put up with this for a while and if it bothers me too much later I'll turn on the second screen. Other screens I've installed come with "alignment" stickers. I think they would be amazing for that and I don't think the cost of adding them would hurt the company. And as the title says, I can't even tell the difference as far as touchscreen sensitivity goes. In general, fully justifies its price.
