I just got my Defender case yesterday and promised some pictures, so here they are! Let me know if you want pictures from a certain angle or whatever and I'll do it.
The first picture here is a completely naked phone. The second is with the Defender case on. Just to show the difference in the thickness of the case. It adds a good amount of bulk, but I still don't have much issue with having it in my pocket.
It's bulky, but I don't mind at all. People are always asking what phone it is because it's so big, but I take the case off and they say "oh that's not bad."
I'd just rather have it well protected, and with this case it is.
