**** of a good question there. I have one as well and would like to know, I am a General Contractor and I would not have a phone anymore if it were not for my otterbox. Stay safe out there!

If you bought it and it says it has a lifetime warranty, I don't think they can take that away from you once you bought it. What you do need to be careful of is who's lifetime it is, yours, the phones, or their expected lifetime of the case? I think some people say lifetime, and mean lifetime of the product they are selling, and they could deem the products lifetime at 1 year if they wanted. Read the fine print.
