The Trident Kraken iPhone 4S case offers superb protection. The case consists of three separate components. The main component is the rubber substance that surrounds the iPhone completely for protection. This could be used as a separate case to protect the iphone by itself. However, combined with the Exoskeleton, polycarbonate pieces that are included the iPhone is completely protected. The case also has a kickstand on the back used for standing the phone up for watching videos and such. All of the buttons and ports are accessible but most are covered by some type of rubberized protection. The headphone jack has somewhat limited access. They do include an extension for reaching the headphone jack for fixing the problem.
The Trident case is one of the top contenders for protection. I have been in an OtterBox defender fan since its release. However, the Trident Kraken case is an excellent selection. It is one of few that offer the type of protection I expect from a case. The case is available at www.tridentcase.com for $49.95. It does include a screen protector as well. I have also included a video demonstration installation below. Feel free to leave any comments below.
