These days, there are tons after tons of these screen protectors each claims to be 'perfect' and 'best value'. I consider Spigen a reputable seller and I have tried quite a lot of different glass screen protectors.
I like this one for the below reasons:
1. the fit is prefect. The top, the bottom, as well as both sides of the screen is covered perfectly, which is not the case I am having with some other 'cheaper' internet brands
2. The edge is properly curved. There are a lot of swipe-from-the-edge hand gesture required for iOS 10 and I like the fact that the side of the glass is rounded and won't cut my finger.
3.The screen protector is coated with some sort of good quality coating. I think this is specifically important, as an average consumer, I cannot tell what fancy material they've used to coat the screen but I do notice the glass is fingerprint resistant as well as scratch resistant.
In short, quality does come at a a price but this one is very comfortable to swallow. I would say it is your safe bet to buy from known brands like Spigen than just wanting to save a few quid and end up with poorly constructed protector..
