Review on 📱 TOCOL 3 Pack Tempered Glass Screen Protector for Samsung Galaxy S7 - HD Clarity, Touch Accuracy, 9H Hardness: Easy Installation Tray Included by Chadwick Webster

Guide tool makes installation easier. You can usually easily apply these screen protectors and they seal themselves, except for the edges, which you can repair by simply running your finger along the edges. According to the description, it doesn't smudge. I can't say if that's true, with my oily skin it depends on everything. Good product. 10/10 recommend.
