I have said this before and I will say it again. I have an S6 and have bought my Tempered Glass Screen Protectors from ebay. I am in Canada, there is a guy that sells all brands and I get them dirt cheap. I have had it on my S6 since I bought it, in June of 2015, and it looks great, and is still protecting my phone perfectly with no scratches or cracks. I think I paid all in 6 bucks Canadian.
I don't see the point spending 40 bucks on a protector because if a name. If mine has lasted this long, even if it broke tomorrow I would be happy to spend another 6 bucks rather than go through warranty after paying 40.
I mean come on? You can't go wrong
