Review on Premium [2 Pack] Tempered Glass Screen Protector with Black Bumper Case for Apple Watch 44mm Series 6/SE/5/4 - Full Coverage, Easy Installation, Bubble-Free, by YMHML by Chris Drury

This is not tempered glass as it flexes when tapped and feels and sounds like plastic. It doesn't look like glass at all. They also fizz every time you even get in the water. You can't swim or shower with the watch, or it fills with water, creating a very annoying bubble. Then the touchscreen no longer works. There is no glue on the plastic at all like ordinary screen protectors. On the way home, one of the covers came off, either with the luggage or on the plane, I don't know where. I gave it 2 stars as it protects the watch but makes it difficult to use especially when swimming or showering with the watch.
