I got a case for my iPhone 4 a year ago. The cover broke on one corner and I submitted for a replacement on warrantee online. Within 4 days, I had my new protection case delivered to my home at no cost by FedEx. I could not believe how well this company stands behind their product which I really like as it protects my phone extremely well.
I bought this OtterBox less then a year ago and I am now on my third one. It always breaks at the same place around the headphone jack. Also if you try to clean the white rubber part of the case you can't it clean. Then when you order your replacement I can't get another colour when others can.
This case is definitely the best out there. It is not too bulky to keep in my pocket, yet it has ULTIMATE protection from drops and whatnot. I recommend it to everyone I know, no matter their type of phone.
I love how Otterbox backs their products I just wish I didn't have problems with the case. I am on my third case and they each break in the same spot. (The narrow strip on the hard case across the bottom of the phone.) Each time Otterbox has stood by their guarente and replaced my case but I just wish it would stop breaking! I am not that hard on my phone. I guess I should try one of the more durrable types of cover.
