What smartphone case do you advice?

ciganie

Hello everyone,
I ordered a fresh iPhone XR and looking for a shell to defend my iPhone.
Do you have any good recommendations for nice and durable mobile phone shells?
I've been searching for a few hours but I still can't decide at all!
Apple provides nice products and so expensive.
I heard from parents that these smartphone cases are not enough firm.
So I'd like to purchase very robust mobile phone shell that save  mobile phone for many years.
Any recommendation will be  appreciated!
Thank you so much for your advice!
