After reading a lot of detailed review information, I chose FLOLAB protectors for three new iPhone 13's (two Minis and one Pro Max) and my experience installing them onto the two phones at my location only confirmed my hopes (one of the Minis was far away with a family member). The application tools provided were superb and resulted in easy precision alignment, as required when using a full-area coverage protector (black edged), where misalignment of more than about ⅓ mm or even less could cause the lip of the front edge of the case to bump into the edge of the protector.
Do plan on using your best dust management techniques to help prevent dust getting between the cover and the screen. 1) Watch the FLOLAB instructional video a couple of times 2) Work in a less dusty location 3) Wear clothing that doesn't shed much 4) Use a bright flashlight to show up dust really well 5) Maybe use a duster for squirting away dust a few times (but please not one that's a super greenhouse gas - some of them are terrible that way!) 6) Work quickly so dust doesn't settle on the surface just before you set the screen down. Having a helper to hold the flashlight helped in my case too.
The plastic alignment frame to guide the protector application process fits the phones very snugly and the opening in the frame is perfectly sized to match the protectors, at least the full-coverage ones that I purchased (I don't know whether the smaller coverage protectors come with correspondingly smaller-opening plastic alignment frames). So they were gorgeous once applied. Very clean and shiny and good-performing oleophobic coating. These protectors also provide an excellent balance of shatter and scratch resistance in testing. Overall a big winner from a company that I had not known about from the last time I shopped for screen protectors even two years ago. Highly recommended - best overall product and lower price at the same time.
