The Krypton Flex case is a great, easy to use, protective, and stylish case for the iPhone 3G and 3GS. This case is easy to take on and off due to it's rubber material, while covering the iPhone in every necessary place and looking great. The Krypton Flex Case comes in four different colors and designs: Orange Groove, Black Groove, Black Pyramids, and White Spiral. I have been using the White Spiral case for about a month now and I love it.

The case is made of 100% Silicon, which allows for bending and stretching of the rubber to easily fit over the iPhone's body. Numerous amounts of cases I use are great, but they are challenging to get on and off. For some, taking a case on and off is not a big deal because they do it rarely. For someone like me, who is constantly changing cases, this case makes switching a breeze.

From what I have heard, people have the misconception that rubber cases are not very protective. This is not the case with the Flex Case. Sadly, I drop my phone on numerous occasions. Back when I had a first generation iPod Touch, I did not have a case, the touch is now missing the back, the screen is cracked, the headphone jack is ruined, and the wifi doesn't work. I have dropped my iPhone in the Krypton Flex Case loads of time, with no damage to the phone. I also did a few drop tests from 3 feet, with no visible damage. All around the Flex Case is highly protective.

The case has now covered everything that is needed in a case; protection with style and ease of use. While being protective, this case does not sacrifice functionality. There are openings for the headphone jack, speakers, docking port, camera, and ringer switch. In addition, there are rubber buttons for the on/off button and the volume control. For style, the case is great, the White Spiral design is simple and in my opinion great looking.

Overall Krypton's Flex Case is easy to use, protective, and good looking, while maintaining functionality. If you are looking for a protective, attractive, and functional case I highly recommend the Flex Case by Krypton. In addition to all of this, the case is easy to clean, has a nice grip and is very practical. This is my favorite iPhone 3GS case and I have used tons.
