After I've wasted a lot of money on expensive branded protectors, I gave FoliX a chance and what can I say: the screen protectors keep in every way at a fair price, what is promised by the manufacturer. The film is a guide with quite useful installation tips in, plus an inserted welded-microfibre cloth and in 2 minutes you have the film mounted perfectly without bubbles. The assembled film is so transparent that the excellent monitors of Olympus lose nothing of their sharpness and brilliance pure; the films are optically almost invisible. For me it is clear: in future, I trust only on atFoliX products if I need screen protector again! Strong buy recommendation.
