One piece snap on cases are simple, minimalistic, and add a splash of style to your phone. Newer Technology provides all of this in its NuGuard Carbon case. Snap on cases are some of the easiest things to get on your phone. With the NuGuard Carbon, just slip in one side of the phone first, preferably the side with the buttons. Then just push the other side into the case until it 'snaps' together. If you need to get it off for any reason, I find that separating the case from the phone on one side and then pushing the rest out is the easiest way, and is usually the standard way for snap-on cases.

The sides of the Carbon have a soft and smooth texture that gives the device some grip, which is always good to have considering that the iPhone 4's glass can make it slippery. The back is covered with a carbon fiber pattern that adds a sense of style and texture to aid in getting a good grip on your phone. The ringer toggle and volume buttons are super easy to access with the exposed space for them, so there's no trouble getting to them like with some other cases.

Since the top and bottom are exposed, the NuGuard Carbon has no trouble giving you full access to the charge sync terminal and the power and headphone jack. The camera is given an ovular cutout that gives the flash enough room without obstructing photos in any way. The only drawback that I can see of the case is that the top and bottom of the device is left open. This means that if the phone is dropped and hits a surface on the top or bottom, there isn't any protection to save it from cracking or scuffs. But it shouldn't be a problem for those that are careful with their phones, like I usually am.

If you're looking for a simple and minimalistic case that will give you some protection while looking good, then the Newer Technology NuGuard Carbon Fiber could be a good fit for you. Just be careful with the top and bottom of the device. You've been warned.
