Lifeproof & Otterbox Cellphone Cases

I found the Otterbox iPhone 5 case on ebay for the same price and free shipping. Saved me five bucks.

What exactly does a 1 yr warranty on a lifeproof case look like? Is is just against manufacturer defects, or does it include damage to phone that is deemed protected by the case?

I bought one of these from Woot a while back. I don’t use it because the switch to turn the phone to vibrate on/off doesn’t fit properly. The only time I will use it is when I’m on a boat.
