If only the world of YouTube reviewers would learn the value of tested-in-the-field reviews. "I've been using this for a week and I give it five stars" is so dumb. I've used a pretty good phone screen protector from Gadgetshieldz for over six months now and here's my damn-sight-more-useful review.
My newish Nokia 8 needed protection. I buy devices for their aesthetics and function, so I hate covering them up with chunky cases, but I don't want them scratched to hell by being naked. I found some positive reviews for the Gadgetshieldz product in a few places (YouTube and XDA) and thought it was worth giving a go after discovering that the Nokia 8's screen was too curved for the usual tempered-glass screen-protector strategy.
