The packaging comes with a qr code that you can scan and watch a video. The instructions are very clear and everything is provided to complete the install.
Months of up scrolling slowly pushes it up in the middle. Once over the earpiece and bumping up against my case it starts to peel off. Shield not even noticeable.
But the slippery coating on it wears off. This leads to bubbles and wrinkles on one or two edges, and exposes the glass on the opposite edges. Got dust in it. But it is made out of the cheapest plastic.
These screen protectors are legit amazing! They give you two screens in case you botch the first installation. Durability as far as most types of * is really quite good.
Saved my phone screen from cracking a few times. No misaligned edges. Comes with a little cover you put over your phone to use as a guide to put the screen protector on perfectly!
Easy to install with the included guide, wipe, cloth, and dust removal sticker. I have a 11pro max in case it helps.
