Nice matte color, it has protection around the cameras and not on top of the lens. (They avoided the problems caused by the glass on top of the lens) It only fits with Ringke cases. The negative thing is that lint sticks to the adhesive around the lenses and it is difficult to remove. Also, it only has one inside (other companies have two), so in case you put it on crooked, you have to buy it again.

It is perfect (especially for the black S21 Ultra) because it is exactly like the device's camera bump, metallic black with the same texture. Just what I wanted to put on, so that I have peace of mind that the metal around the cameras won't get damaged, without affecting the quality of the photos like I see happening with all the others that have a glass protector over the lenses. It's like a safety measure so that if something happens, the protector will get scratched and not the device! Of course, it fits perfectly with all Ringke cases. With the Onyx (like in my photos) and the Air that I have tried, it sits deeper inside the case so it won't touch the table, for example (the protector) if you're using a case. It definitely fits with Samsung cases as well, but maybe not with all Spigen cases, or they will just sit on top of the protector... I highly recommend it!!

Update 9/2021: I put it in and take it out of my pants and jeans pocket more than 10 times daily, and with frequent cleaning (I'm obsessed), it hasn't suffered any damage, it still looks like in the photos.

Update 3/2022: I removed it a while ago, and it left marks from the adhesive that required a lot of effort to remove! Luckily, it didn't leave any permanent marks, adhesive residue, or damage. So, I DO NOT recommend buying it!
