I have a thing with screen protectors on my phones. I hate them. But I also know how hard I am on phones. I've been searching for a glass one for my iPhone plus models that isn't too big and fits right.
Went out on a limb and tried the Spegien brand from Amazon. Under 10 bucks for a 2 pack. These fit amazing. They were cut perfect for the phone. I go through glass screen protectors about every 2 months. I re-ordered 3 more packs today.
If you're in the market, give this a shot.
