We got the Abstract Ocean matte one - you cannot tell its on there. It warns about potential loss of resolution, but you wouldn't know if it did or not.
Not as easy to fit as the video made out though - took me two attempts and a few heart stopping moments as, no matter how many times we cleaned it, the screen just wanted to attract that one tiny flex of lint - ironically from the supplied cloth. Second time around we used the screen cloth that came with the car. The supplied bezel should make it nigh on impossible to misalign, but do a 'dry fit' first.
It dramatically reduces/eliminates specular highlights and greatly reduces diffuse reflections - you still get sun glare though at some angles. You can still see finger prints in some lighting conditions but easy to clean. Certainly no longer the finger print magnet that the original screen was.
I can highly recommend the AO matte screen protector. Just don't use their supplied white cloth.
