I saw the thread on the Lifeproof nüüd for iPhone 5s, which was very helpful in learning about that particular model. But, I haven't decided on which Lifeproof case, the frē or the nüüd. Does anyone have experience with both and have any tips on the advantages/disadvantages of one over the other, or which I should buy? Both models seem cheaper on Amazon. Any disadvantage to not getting a case directly from Lifeproof?
