Lunatik's New Taktik Extreme Case for iPhone 5
When it comes to the safety of your precious iPhone 5, most of us would stop at nothing to make sure happens to our precious device.
That being said, If you are totally paranoid about extra-strength security for your device then the Taktik extreme may very well be the case for you.
The case features Corning Gorilla Glass over the screen of the device and over the camera and still takes high quality photos perfectly while keeping the full responsiveness of the iPhone 5 screen.
It is also completely water-resistant and will shake off dust and sand with ease, along with some of the best anti-shock technology in the industry!
Lunatik also have a couple of other cases coming out at CES 2013 including the Taktik Strike and a Seismik Cessation Frame
The price and release date for these accessories are currently TBC by Lunatik themselves
