Fit to screen is not precise. Protector's surface area is too sticky to use the standard rubber nib on the S-pen, and too soft to use the plastic one - it leaves marks on the screen. Not recommended.
The size is not exactly correct for the screen. The surface of the guard is too sticky to use the eraser tip of the S Pen and too soft to use than plastic because it leaves traces on the screen. I do not recommend it.
