These are good value but I think you will certainly need 2 of them! I have used scree protectors from Zagg, Spiegen plus horrible OEM ones so I do have experience in this area. Alignment on Note 3 gave me lots of problems and in trying to realign I manages to get a dust spec on the adhesive, the supplied dust removal sticker was no use. The quality vs price is good but please don't think these will be any easier to apply than any other branded 'dry' screen protectors.
This is a low quality item even at £26!!! It is actually a German company although I could not find much info about them. The use of the Norwegian colours etc is bit misleading in terms of the overall quality. I returned this item.
