Review on Tensea Fitbit Charge 3/4 Screen Protector and Case Cover - 2 Pack Soft TPU Bumper with Full Coverage for Fitbit Charge 3/3 SE and Charge 4 (Blue/Clear) by Maria Hanson

1. Yes, water penetrate (nothing is bulletproof)2. Yes, it gets scratched easily (thanks to something it's more of a user problem, it's better than getting your screen scratched. I'm a rude person and a clumsy person, so of course it gets scratched, which is why I have a screen protector)3 . Dark Screen: When I first put the screen protector on the watch, it was dark. This is not the fault of the protectors, I just had to increase the brightness of the watch. Overall I like this screen protector. It has no bubbles and I don't have to change it every month like I have with other screen protectors. Like I said, I'm an active person, so has my scrapes, but the toothpaste will take care of that. I love that it comes in multiple colors because sometimes I don't want my watch to be rose gold with certain straps. It does what it's supposed to, protects the Fitbits screen.
