The PureGear is a more heavy-duty case with a unique three-layer design that snaps over the front and back of your Galaxy S4. Using an included hex tool, you snap on the case on and then secure it using the screws. The case is rated at IP54 for being dustproof and splashproof and at the 810G military spec for impact- and shock-resistance. The case is made from a rubberized plastic and only comes in black. There’s also an iPhone 5 version available. This case cannot be fully submerged, but it’s water-resistant and splash proof.
