I apoligise for the length of this but I have never run into a company this blatantly corrupt. I have never written anything this critical but it is the kind of thing I would like to have seen before I bought stock in Enron. Hard to believe, I was skeptical when this company was identified as a sham on forums, but they seem intent on defer ,deny and deceive. Lifeproof is as of today still not refunding or replacing known defects to some customers including ones within warranty time frame and is deceptive enough to say they will replace and then fail to do so.They have had every chance to become transparent about problems and fix them and continue to act in the same irresponsible manner. If this had been a medical or life critical device there would be bodies everywhere. Here is taste of their feedback: This seemed to be a cool product with a fixable flaw [distorted or absent microphone reception} that a bad company messed up with deception and fumbling. 1 Lifeproof denied warranty lying about purchase in warranty period. It was referred to them well within their 90 day period. 2 Lifeproof failed to replace or reemburse for a well know defect and instead told warrantable customers to purchase a full price new one. 3 Lifeproof, when exposed for their misconduct, promised to replace defective items, another promise they have failed to act on. In early October 2011, I purchased an iPhone 4S and I take my previous iPhone to have the screen repaired in order to give it to my niece. The technician recommended a LifeProof case at Best Buy and he said that probably would have that would have prevented the glass screen on my old iPhone from breaking. While he is making the repair to my old iPhone, I go to Best Buy and purchase the LifeProof case for my new 4S. All is well with the new iPhone and LifeProof case. I notice it takes a little more pressure to make the apps work through the LifeProof screen but no big deal, I quickly adapt. A couple of weeks later, my wife and I take a flight from Dallas/Fort Worth airport to Savanna, Georgia and we return home a week later. I didn't use my iPhone 4S for making calls while we were gone, except to use the mapping apps while in Savanna. It's now the first week of November, and as I use my iPhone 4S for making calls after the adventure in Savannah, the audio is muffled. People I call are complaining that they are hearing their own voice being echoed when they talk back to me. Some of the calls I place to people, my own audio is so distorted that people can't understand me. I suspect a problem with my new iPhone and I Google "iPhone 4S distorted audio", iPhone 4s audio echo" and I find numerous sites where people are complaining about their new iPhone 4S having audio clarity problems as I have experienced. I call Apple and they arrange to have my iPhone 4S sent back for warranty repair. A few days later, the replacement iPhone 4S arrives, it checks out fine and I place it back in the LifeProof case. All is well for a number of days, the iPhone works fine. I make a quick trip to Colorado, return home and the next day, I call a businesss in a nearby town. The person says repeatedly "hello, HELLO" and then hangs up on me... I call my wife at work and while she recognizes my number on her iPhone, she can't understand me because my audio is so garbled. I call Apple and talk to them about the garbled audio and I advise them this replacement phone only holds a charge for ½ a day. Apple graciously sends me an overnight box to return my iPhone 4S. A few days later, the 3rd iPhone 4S arrives and the battery on this 3rd 4S runs nearly two days... I'm a happy camper with two days use on the 4S. I place the 3rd 4S back in the LifeProof case... everything works out fine. A week later, the dreaded audio feedback, garbled audio returns. I call Apple and ask them what my problem is. This time the Apple rep suggests the problem is with AT&T. I am so frustrated at this point; I purchase a TracFone and use it until I can make the 100-mile drive to the AT&T store and advise them Apple suggests the problem with my terrible audio is on their end. The store manager directs me to one of her reps (a savvy retired Air Force guy) and I explain my problem to him. He takes one quick look at my iPhone 4S and says, "Here's your problem. The LifeProof case!" He tells me to go outside and to call him on his phone. Sure enough, he can't even understand me. He motions for me to come back in and he removes the LifeProof case asking me to go back outside. I call him again and the audio on both sides is crystal clear. PROBLEM SOLVED... I go home, get online to LifeProof and advise their case had been causing severe audio feedback and echo problems (and I am not the only customer affected...) and I advise I have just changed my 5 star review I left on Amazon to a 1 star review. She advises that they are "no longer" marketing LifeProof cases through Amazon. Had you purchased your case at BestBuy, we could have replaced your case with a new one." She never offered me any explanation, did not offer to exchange my case and I was stuck with this defective product they flooded the market with. LifeProof (in their wisdom) gives this "corrective fix" to customers in regard to their inherent defective cases... "Blow hard into the microphone for about 3 to 4 seconds. The sufficient effort require(d) is akin to blowing a candle out. You could also pretend you were blowing up a balloon by sealing your lips over the hole and then blowing." Well, many people are tired of having to blow into their defective LifeProof cases several if not dozens of times per day (Google for yourself and especially on MacRumors) I bought a lifeproof phone case three weeks ago from Bestbuy The case is expensive for what is . The lifeproof headphone jack covers fell off after using them and screwing them back in...Bestbuy would not supply new ones or give me a new cover. Great customer service by Bestbuy....would never buy from them again. I needed to buy new phone jack covers from Lifeproof who charged me $15.00 for a .05 cent item plus over $9.00 in shipping....big ripoff. Stay away from Lifeproof! Furthermore, I did research and you can now get your phone waterproofed through liquipel for $59.00....seems like good new technology.
