Well my experience is different. Granted, the iphone 7 plus was probably not quite as delicate at the X but I dropped mine several times in the last year and the case offered great protection. The phone was perfect when I sold it.
I have used these apple leather cases on all phones since the 5S and now have it on the X. For me they offer a good combination of protection and style and they are not very bulky.
There is a lip all round to protect the phone, open bottom or not, however if the ground is particularly bumpy and the screen hits a stone then it will likely smash. You could say that about most cases though except for the very bulky ones.
