I take this film from mumbi already on many devices (smartphones and tablet's) and have to say I would never go back. They are not quite as lapprig like many others and if you take the hang of it, also easy to apply. I myself at first hand a couple of tries, but now I rarely have a problem. Qualitatively, the surface is good, but in the anti-reflective coating is the haptic more limited than in the Crystal finishes. But outdoors with where often the sun is a bit strange in the game, is an anti-Refelxoberfläche clear advantage compared to the Shining. Well priced I have nothing to complain about, because I've already bought far more expensive films with less "power" also from experience out there and these have then later replaced by that of mumbi.
My Conclusion: Outdoor smartphones this antireflection film with good visibility and good protection - other smart phones like the Crystal film from Mumbi.
