The film fits perfectly on my Surface RT, the recesses are exactly in the right place. In addition, the film is very tolerant to repeated stripping and re-hang (the dust, the dust ...), because I had to remove with Tesa the last little speck of dust. I do not see any really noticeable degradation in image quality, you have to make the screen a little brighter than you have without the foil. The overall impression with the matt display also like it much better than with shiny Schrim, but that is certainly a matter of taste. When operating one notices no difference to the operation without foil, responsiveness of the screen as with both finger and pen with is very good.
