Tempered glass screen protector
Hi,i was thinking of purchasing a tempered glass screen protector for my xperia z1.
I was thinking about nillkin but the problem is that it has a plastic back cover.Is that scratch resistant?
There are many brands available in the local store but how do i know if the protector is good,they widely vary in prices.Is there any way to know if a protector is good other than its price?
Is there any serious disadvantage in using a tempered glass screen protector?
