I gave it 5 stars because:
1) It fit perfectly on the screen, easily without any bubbles.
2) The fingerprint function on the screen works perfectly.

This particular glass protrudes slightly millimeters from all 4 corners, so you need to be careful with the case you choose because it may press on the edges and cause the glass to bubble. For example, in the case provided by Xiaomi, this glass does not fit because the back cover of the case needs to be relatively low.

Also, it requires a good amount of pressure (with caution) after installation in order for the adhesive to spread well.

The installation is relatively easy because the selfie camera circle helps you position it correctly. It is durable and provides a clear image. You can also watch related videos and tips if you attempt to install it yourself and it is your first time.
