This is a very good value glass cover.It comes with 2 sets of glass (in case you make a mistake or in case you needed a spare to replace the current when it's damaged), cleaning kits, back carbon fiber skin cover, lens protection shield, and a plastic glass installation guide.I have read from other comments that some people complained about dust going under the glass. I say they are ridiculous. Ibywind does not control the dust in their homes.Anyway, if you really want to install it with very minimal dust, you keep the stock cover (Xiaomi Poco F3 comes with a pre-installed protector) until the very moment when you are about to install the glass.Follow the steps below as a guide for the best method of dust-less installation.1. Select a sealed, well lighted room that has no air movement. If it is a bathroom, turn off the ventilating fans or exhaust fans.2. Let your steam run until it reaches around 85% humidity. Vapor can adhere to dust and make them heavy so they fall on the floor. (if you don't have a steamer, shower first with hot water. Don't let the steam escape)3. Use tight-fitting gloves. This is important to avoid leaving oily residue on surfaces.4. Clean the entire phone with electronic cleaning solution.5. Wipe with a clean microfiber cloth (I used the microfiber cloth that is used for cars. See picture)6. Install the Camera lens shield on the back.7. Install the back carbon skin (or not if you don't like it)8. (I did not use the plastic guide) Pull plastic film halfway such that the end with the hole is resting on its edge. Then push on the surface to initiate contact.9. Continue to the other end, and keep applying pressure on the center.10. If there are bubbles, don't push it out using the cloth, instead, peel off the portion where there are bubbles and keep putting pressure on the other end that has a good coverage.11. Repeat until all bubbles are gone.The only cons I have with this protector is that although they claim that the edges are curved, it seems that the curvature is not enough because there are still noticeable lifting at the ends. (See picture)This might not really be a deal breaker since the glass is not permanent and I don't check my phones by looking at the edges anyway.I think it's a practical approach that we should not expect perfection from everything, even from the most expensive ones. What this does is it protects the screen from potential scratches, which is really the main purpose here, for an affordable price.In the end, it doesn't really bother me that much because videos very rarely exceed 16:9 ratios and Poco F3 has a screen ratio of 20:9, which means the part with the lift will always show black. And I never read anything at the extreme edges.Overall, I am very satisfied with this protector and I will buy again for spare purposes (I actually broke the other one to see how durable it is and I was surprised that it did not shatter. It seems like there is a layer of adhesive on the other side of the glass that keeps the glass from shattering)
