Well, I just installed it and with a little effort, I managed to avoid any bubbles!

On my first try, it created several bubbles and I removed it (don't be afraid) and on the third try, I succeeded.

The method I followed is: With the left hand (index-thumb), you center and hold the screen protector above the screen. You first stick it in the middle of the screen (don't let go with the left hand) and carefully push upwards with the index finger of the right hand while slightly lifting the edges (with the left hand) so that it gradually sticks. Then you do the same on the other side (the other half of the screen). If you see a bubble forming, you push it upwards with your finger to get rid of it, and if it doesn't go away, you peel it off a little (with the left hand) and try again by pressing upwards with your finger.

If you see that it didn't go well, peel it off and start over.

It requires patience. It is much more difficult to install than the screen protectors for mobile phones, which now rarely create bubbles as long as you center them correctly.

Be careful not to trap dust or dirt inside.

If applied correctly, it is not noticeable at all due to the black frame it has, although for it to be 100% perfect, the frame should be slightly larger.

It is not a "glass" like the protectors for mobile phones, but a hard-resistant plastic.
