I preferred to get the authentic Apple© case instead of its excessively high price for what it is.
1. First impression is good and the magsafe design is beautiful and proper, not like cheap cases that are just prints.
2. Thick plastic and it seems like it will protect the phone in case of a fall.

NEGATIVES
1. Good build quality but not in relation to its value.
2. It slips excessively and with the extra weight of the phone, it is risky. I happened to hold it in my hands at the beginning and it slipped on the table. (fortunately not on the floor).
Overall, it leaves you with a feeling of having oily hands.
3. It does not protect the bottom part.
4. The buttons have a hard feel and with one hand, you have to give good resistance to press the power button. Combined with its slipperiness, it is catastrophic.
5. It is relatively difficult to remove and you have the feeling that you will damage the phone.
6. I forgive all of the above, but I will never forgive the fact that the authentic Apple© case does not fit perfectly. It fits well in the corners but there is a gap on the sides and it creaks when you simply hold and handle the phone. I still have 4 cases, both Spigen and Ringke, and they fit much better.

I don't know if it yellows over time, but it seems like I will never find out since the case has been returned to its box. I don't think I will use it again.

It is a case that if it was priced up to 20-25€, I would justify it just for the magsafe. But for 50€ and made by Apple© itself, I cannot justify such a poor case.

I would not recommend it and I wish I had the ability to change it. Personally, while I had it on my phone, it greatly spoiled my user experience. I cannot have a 1,500€ phone and wear a case that creaks.

The only thing you need to be careful about is that it is quite slippery.
Also, I don't see any oil-repellent coating.
It is a material that I have never seen before.
It is hard and all around, but not plastic.
I really like this because it doesn't yellow over time.
Very beautiful and very durable.
Ideally, I would like it to have bottom protection, like all genuine Apple cases from the 12 and onwards.
Only the transparent ones have a gap at the bottom.
Of course, it is considered protective for the camera and the screen, as it protrudes to protect against falls.
And even at the bottom, where it is empty, it has a small part that leaves uncovered, and the bottom part of the case protrudes quite a bit from the bottom of the device, so that in case of a fall, it does not touch the uncovered part of the phone.
The buttons are soft, very convenient, neither thin nor thick, just enough to be protective, as I want it.
High-quality material, and this is missing because it is both expensive and Apple.
They should get it (for me it's worth it) but,
Those who overcome the issues
1) That it is quite slippery
2) That it leaves the bottom part uncovered (even a little, but it does)
3) That it is a bit of a fingerprint magnet
4) That it is very expensive and the truth is that at half the price, one can find something similar with protection at the bottom.
But, it's Apple and it's a guarantee for me.
I have a preference for Apple cases in general.
I had a transparent Apple case on my previous model, 11 pro max, it wasn't MagSafe, but it was made of the same material.
It never yellowed, never scratched, I took it off very often because I changed cases as I get bored quickly and I want variety to switch, and it didn't break or get damaged even though it is a hard material, in general, it is very durable!
I wonder how it breaks so easily for many people I read about.
That's it, I hope I helped.
