it's not about the price, and i was looking for something like the Rhinoshield or Phantom glass but phantom glass doesn't have one for the S7, and as i said the Rhinoshield leaves too much edge. i don't know what they are made of, but the Rhinoshield i had was almost impossible to scratch. so basically i'm looking for something to be very good protection for my phone and i don't have to replace for 2 to 3 years if i don't break the protector of course
UPDATE: i just heard from phantom glass that they just released phantom glass for the samsung s7
