iPhone 6 (4.7 inch) HD Clear Ballistic Glass Screen Protector by Guardian Tech is a great Glass cover. I have always had a hard time putting on regular covers and I always had to take them off because they left bubbles. I now have put on 2 Tempered Glass covers and they came out perfect !! Just follow the easy instructions and if you take your time you can make your cover perfect to.
Clean the surface use the cleaning wipes so your screen is spot free and dust free. Start on one side and just slowly push down going slow. I am so happy with my cover it is actually perfect that you cannot even tell that it is on. I received this Ballistic Glass cover complimentary in exchange for my unbiased opinion and review.
