I am on my second Armor Series Case. The first one wore on the front bottom (rubber edge) and eventually the rubber seal completely wore out. I am sure it is because I kept it in my front pocket. The same is starting to happen to the new case (which by the way Otterbox replaced for free after I followed their return policy). This is by far the best Otterbox case I have used. I used to use the Defender Series but I am really tough on my phones. My phone is completely sealed in this Armor series and I even dropped it in the toilet. It was totally protected. Forget the Defender Series and spend the extra $$ on the Armor Series.
Pros: High quality
Cons: needs to get the rubber off the front bottom.
