Well, I replaced the screen on my phone twice before I bought a case. I've dropped my phone many times, both before and after I got the case, but with the case it doesn't seem to get damaged. I got the slimmest case I could find, so it's definitely not bulletproof, but it makes a difference. I'd guess I've saved myself one screen replacement so far. It's maybe 1.5 mm thick, just a touch higher than the volume buttons on my 4S, so it doesn't add much bulk. This anecdote not the double-blind replicated clinical trial that HN seems to insist on as a rational basis for believing anything, but it's enough to convince me to keep using the case. There's such a thing as being too skeptical.
