I have already ordered many scratch-resistant and anti-reflective films for diverse devices. Maybe I'm spoiled by "Vikuti", but this one is very rough, has a large frictional resistance and attracts fingerprints. Otherwise sufficient, let's see how long it lasts, will cost only a quarter of a Vikuti film :-)
UPDATE 24.04 .: response from the manufacturer promptly with Note that rough feeling soon disappears / possibly due to production.
