Are you sure?
This product supposedly provides also: Anti-Abrasion:
Crystalusion™- Liquid Glass Protection forms a nanolayer of liquid glass over the treated surface. This liquid glass layer is exceptionally smooth and very hard so it is able to withstand scratching to a higher degree than most untreated surfaces. It is designed to withstand day to day abrasion and reduce the likelihood of scratch damage.
I see... I think I'll try it anyway.
I can no longer use tempered glass protectors because they alter the polarity of the screen and make it invisible when wearing polarized sunglasses... and I can't stand the regular, film, protectors
I'll keep you guys updated.
A quick update - I received the crystalusion shield. The application was easy, you just clean the device with the supplied sponge and then, apply the shield with the other supplied sponge. after a few hours (the manual says 12 hours...) you gently wipe the device with a microfiber (also supplied) to remove any leftover residues and that's it.
Now, we wait...
