Hey all. I just bought a new iPhone XS Max and want to protect my investment with a tempered glass screen protector and want to know where to go to buy and have it installed. I want to make sure it's installed perfect or it'll drive me nuts. Do these stores use a machine to install them and is there any store in particular that has a warranty or something where if the phone needs to be replaced or something like that that a new one can be put on with no cost to me? Thank you in advance!
