For the first time, Seidio has set foot in our humble abode with its first waterproof case for the iPhone 5 dubbed the Obex. LifeProof is no longer alone in this rapidly expanding market of slim waterproof and drop-protective cases for Apple's iPhone. Seidio's Obex and Incipio's Atlas are the two most notable, and intimidating rivals that LifeProof is now facing, and for good reason. The Obex waterproof case for the iPhone 5 had to pull out all the stops in order to win over the hearts of new iPhone 5 users looking for that next best all-proof of a protective case. We're super excited about Seidio's Obex and some of the innovative improvements it brings to the table over one of the most favorable and notorious waterproof cases made by the one and only, LifeProof. Find out how well the Obex stacks up against the Fre in our full in-depth review after the break!
