I just found a great deal on Kinja Deals: Anker’s Premium Tempered Glass Screen Protectors for iPhone 6/6s and iPhone 6/6s Plus are currently available for $1.99 each on Amazon using discount codes. They are laser cut to the precise dimensions of your phone and fit only on the flat surface (not on the curved edges). Since it is tempered glass, it is as smooth as your screen and the clarity of the screen protector preserves the image quality of your retina display. It boasts a 9H hardness rating (which is apparently harder than a knife) to protect your phone against scratches from keys or other sharp objects. It also has an oleophobic coating to resist fingerprints. I cannot vouch for the quality of these screen protectors as I do not have an iPhone, but if you’ve been looking to try one out, here’s your chance without having to spend a lot of money.
Each package comes with the following: Anker Tempered Glass Screen Protector, welcome guide, alcohol wipe, microfiber cloth, dust removal sticker, and a lifetime warranty. Click on the following links to purchase your desired screen protector from Amazon:
