Online video helped with the installation. However, this screen protector does not play well with Otterbox phone cases. The corners started to bubble up after I put the case back on. The both side also started to peel off from the curved edges of my phone and will not stay down. After one day of having it installed, I noticed smudges on the screen protector itself that won't wipe off. Not an ideal product if you work construction or any type of trades job.
