I purchased an Otter Box Defender top-of-the-line for my new iphone. After several months my phone was not responding to touch. Went to an apple store and the technician tested the phone. He said that the problem was the cover and advised me to throw it away. Once I did that, and used the phone with no cover, it worked fine. I also called the company twice with long wait times -- no one ever picked up the phone, no call back option, could not leave a message, and no message stating how long the hold was. Company says it has a seven year warranty but that's a joke. The company needs to investigated for false advertising.
