Review on NANW Screen Protector Case Compatible With Fitbit Sense/Versa 3, Built-In 9H Tempered Glass Screen Protector Ultra-Thin All-Around Full Cover Bumper For Versa 3 Smartwatch, Rose Gold by Steve Beaumont

It's a great protector for the Fitbit Sense, looks great, easy to install (once I figured out which edge aligns with the button edge of the Sense) it's the edge of the protector with the 2 little notches (which creates a sort of fake button that rests against the Sense button). The screen response/touch input works perfectly with it on, BUT.you will lose the functionality of the ECG app to check for sinus rhythm-- the only solution is to remove the protector-- 2nd BUT-- the protector doesn't come off easily-- you'll need a micro tool to pry the protector off without scratching the Sense's own surface-- be forewarned.
