Good quality glass screen protectors and the included guide piece is really helpful. Made it nice and easy to put on.
But, if you own a pair of polarized sunglasses you need to give this a miss. Looking at the screen, it has this huge green and purple streak through it that moves and gets in the way depending which way you hold your phone.
Take your glasses off and it’s fine, but that’s not ideal when outside in the sun and squinting to see anyway.
Do I recommend them? Yes - only if you don’t own polarized glasses
