Nope don't trust Sapphire glass... It's not as durable and scratch proof as advertised de... That video Gorilla Glass 2 or 3 can do that already lol
Example are watches, they still do scratch easily if you knock it against other surface.
I do trust sapphire glass more than gorilla glass 2/3.
1. my ip5s home button no scratch at all while compare to my glass sp with lots of scratches and cracks.
2. my watch aso made from sapphire glass. i dun handle my watch very well as my job requires me to move heavy stuff, get up n down. no scratch on glass too but other parts other than the glass, lots of scratches.
