I bought it for 0.89€.
It's the 3rd one I've tried.

So far, the application was easy, it had wipes and stickers inside the packaging, while others had nothing...
It also had instructions on the back of the packaging, and they were quite detailed and accurate.
Very good packaging from both the manufacturing company and the store.

I haven't found a 100% full face for this model yet, though. There is always some margin around it.
However, I dare to say that, even though this was the cheapest one I've tried, it is the "largest" and the best and most complete packaging.
In a second comment, I must say that so far I haven't found a good case for this model and I wonder why it's so difficult...

Congratulations to the store for not being greedy and selling the product at a more reasonable price!

I happened to pay a lot for another protective one and it broke in 2-3 months, so I'm taking a risk again and chose this product.

So far, I don't have any specific complaints.
For durability, etc., I'll have to see it over time...
