The only thing I hate about the Microsoft Surface is screen reflections. When using it as a laptop or tablet, I found I was constantly adjusting the angle to minimize glare. This inexpensive screen filter has changed all that. He transformed the surface and made it usable again. It comes in three packs, so you can practice installing your first safe, knowing you'll have two more if you screw up. Can't comment on durability and rarely use my pen, but it seems sturdy. LONG TERM UPDATE: I just had to replace my Surface Book and was appalled at how reflective the new screen was with no protective film. Comparing two screens side by side is like night and day. The amount of highlights it cuts out is incredible. I had no issues with dust or blisters when I installed it and it still looks as good as the day I put it on.
