This is my third defender case - there's nothing better available to protect my iPhone. That said, past Defenders have stretched out over time - I tend to carry my phone in a back pocket while working and that apparently creates some wear and tear after a year or so of use. This one feels like it's made of sturdier stuff. Time will tell.
I have bought otter box cases for years now and would not put my phone in anything other than an otter box case. The only thing that I could say about the iPhone 8 case is that disappointingly the apple logo is not perfectly centereded in the circle window at the back of the phone case. Yes it’s a small issue but it’s the little things for me.
I bought this for my iPhone 8 and am very happy with the standard of protection it offers. It has a good grip and I feel confident that if it did drop ... touch wood a rare occurrence, it wouldn’t crack its glass frame!
