Just an update on the
FloLab NanoArmour Anti-Microbial screen protector.
It's crystal clear and you can't tell it's on the device at all. The only possibly noticeable tell would be that the earpiece is twice as deep and you'd have to see a naked 12 or you'd never notice it. The sides are smooth not sharp like cheap protectors and the cover going over the notch doesn't seem to inhibit FaceID. An added benefit is that with the Apple leather case on it raises the glass so swiping is a bit easier. I've had it on my 12 Pro Max for a few days now and there is not one scratch. It's been in and out of my pocket for 10+ hours a day at work in addition to time at home. It ships from China, but even during this pandemic they had it to me in 5 days. That's a lot better than many other companies at this point.
Overall, it's the first screen protector I think is worth using, I normally can't stand them. $24.99 for a great quality protector is, frankly, a no brainer on a $1100+ device.
