Very good and perfect protective case for the S21 Ultra, both on the front and back of the screen. I also have the Spigen cases which are also good, but they do not have the built-in screen protector. I recommend getting the recommended case

Initially, it protects the mobile phone. There is no doubt.
The negative aspect is the glass. It scratches from a key in the same pocket (OK, you might say don't put it in the same pocket) BUT dust passes through the camera opening and over time it becomes an issue

Very good case, I would say the best.
It protects the glass as well.
It's worth its money, guys. Whoever spent 1000 and above for the phone should spend another 30 to get it.
It protects the phone very well, it has soft corners that absorb shocks very well, and it has a harder frame inside. I have it with a glass on the inside and it works very well. If you have small hands, using the phone with one hand will be difficult because it's bulky. Personally, it doesn't bother me. The first two days it seemed big, but now it's fine. The volume is insignificant to me compared to its protection
