I used to like them a lot and use them. Just recently, however, I dropped my iPhone 8 Plus that I had in a Apple silicone case. I dropped it from waist-height and it fell in such a way down the non-protected/open bottom area, that it left a solid dent near the lighting port. So yeah, not going to buy them anymore.
Instead, I'm now using the Rhinoshield Mod case for my iPhone X and for my iPhone 8 Plus. The protection is much better, the comfort isn't as high, though.
