Review on Ultimate Protection and Performance: CAVN 4-Pack 3D Screen Protector for Fitbit Versa 2 - Full Coverage, Waterproof, Scratch Resistant, and Bubble Free! by John Hall

They give you everything you need for installation except something with a nice straight edge to eliminate air bubbles. I used a credit card by pulling the dial instead of pushing. I used a wet pad to clean the entire dial and then used a dry pad to dry it thoroughly. I turned on the display so it's always on and used the backlit display to align the clear center of the case with it. It was beautifully decorated. Then I made the mistake of following the guide that says not to click the center first, but the edges first. It sounded counter-intuitive, but I followed the instructions and there were air bubbles on the flat surface wherever the display is. I was able to fix this by first squeezing all the bubbles into a corner, then very carefully lifting that corner slightly with the edge of a credit card just enough to break the seal, and squeezing the air into that corner with my thumb, leaving it down again. Then I pressed on the face and around the edges to make sure it stuck well. Now he looks perfect. No bubbles and you can't tell it has a lid on it. I was concerned that lifting the corned beef would cause it not to stick properly, but that seems like a good thing. I showered with a watch and no moisture got under the lid at all. Looks great and I feel like it's well protected edge to edge.
