I picked up the Lifeproof case the day I bought the 4S. I had been using the Defender cases on all my phones for the last ten years. I saw the Lifeproof videos on you tube and wanted to give it a try. I love it much less buld than the Defender and 100% water, sand, junk proof" . I bought the belt clip and love the lock feature. It isn't cheap but quality seldom is. The only negative issue I have is with their customer service. Right out of the box the material that covers the screen had a straight scratch in the material. I emailed them photos and the receipt showing I purchased these items. They sent out just another face peace, after waiting over a week I opened the box and they sent the wrong color. Another email back to them. Now they are going to send me a new case and want me to return the pile of parts. I wish I would have just gone back to best buy, but their instructions clearly tell you not to return it to the store. Everytime I look at the case with the phone off that scratch looks awful. Maybe the replacement will be here by the end of next week. It's been sitting in their shipping dept for 3 days. If you buy one check it out in the store.
