I placed it yesterday on my Xiaomi watch s3. It fits the screen well and it was easy to place. I am not sure how durable it will be and that's why I'm not giving it a 5-star, but it gives me a sense of protection for now. It does not affect the touch functions and the screen looks the same (in a sense that it does not distract me or makes the image worse). It comes with two pieces, a wet tissue, a dry tissue and dust stickers. Overall pretty good product.

Update: One week later I suddenly found a crack on the glass. I am not sure where I banged my watch at. But I am glad the glass prevented any damage to the actual screen so I just replaced the first glass with the second that came in the package and everything looks great now.
