The price is good, however, it does not apply well on the screen, resulting in bubbles at the edge of the screen

Excellent and at a good price.
There are guiding stickers in the packaging. You stick them on both ends on the top side that doesn't have adhesive, then remove the film from the bottom side and slowly and carefully stick the glass using the guiding stickers, so that it is as well placed as if it were factory-installed.
I was also considering other more expensive solutions where there is a plastic frame for easy and correct installation, but in the end they are not necessary.
The packaging of Hofi is also very good. It protects the glass very well so that you receive it in good condition and not broken.
I would buy it again and again!

We first cleaned the screen with a microfiber cloth to remove the dust. Then we wiped it with an alcohol-soaked cloth that came with the packaging. Finally, the application was flawless on the first try. Once it was applied, we pressed in circular motions from the center outwards and all the bubbles disappeared.

The packaging had basic instructions and suggested taking a bath with the device so that the steam could absorb the dust. We didn't try it, but it sounds like an interesting suggestion..

It's fine, it will provide basic protection, right? It's thick enough to allow removal and readjustment if needed. I didn't put it on successfully, it has lint underneath. But okay, I paid 5 euros, it's fine! (The reflections in the photo are practically non-existent, they only appear due to the photography.)
