This did not have a guide, but it had tabs to line up which worked fine was was an HUGE issue for me was the cleaning cloth

Did all the steps and after the alcohol wipe the cleaning cloth left lint that the sticky picked up

(use the soft cloth that is provided with screen protector)

Read The Friggin' Installation Instructions & Follow Them!Personally, I thoroughly wipe down (clean) the ENTIRE screen surface (EDGE to EDGE!) with a soft cloth soaked in a 50%+50% blend of isopropyl alcohol and deionized water until there is no evidence (i.e. haze) of dirt or oil (especially of silicone, which may appear as a rainbow colored film) before applying the protective shield.

The cleaning cloth leaves more lint than it cleans.

Got everything you would need to install, cleaning wipe a cloth, stickers to help place the screen protector and a sticker to pick up dust

Great product, includes cleaning cloths

n’t smooth it out

n’t give me quite as much trouble 🤷🏻‍♀️I will say it did handle being taken off the tablet well; I’ve had other tempered glass protectors break instantly if I tried to remove them, so maybe that speaks to its level of protection.
