This matte screen protector, the effect is significantly reduced. The matte surface is a bit rougher, was initially a little strange.
Now I have either gotten used, or utilization, the surface "greased". Does not bother me (more).
The fit is also good - about 1-2 mm smaller than the display glass from the Surface RT. There are two openings, one for the light sensor and the second (oval) for the camera and camera-LED.
Conclusion: Very good!
