I received my iSkin aura a few days ago, but I had to wait for my new iPhone to arrive to try it out! I ordered the dark charcoal/black case. I was impressed with this case when I saw it on the iSkin website, and was equally impressed when it arrived. Although the back is "brushed aircraft-grade" aluminum, the sides, top and bottom are polycarbonate. It's extremely thin and light, and doesn’t really feel any bigger than the iPhone without a case. The polycarbonate sides make it feel very comfortable in the hand. It has a nice, smooth, “soft” feel without being too slippery. From the iSkin website photos, it appeared that the inside back may be aluminum, and I was concerned about the back glass of the iPhone rubbing against the aluminum and possibly scratching the glass. Especially if dust or small particles of any kind got into the case. However the entire inside of the case is lined in soft-to-the-touch polycarbonate. It snaps onto the iPhone with a firm, snug fit, and provides easy access to all ports and buttons. Although the case looks and feels great, it adds only a moderate amount of protection. The back, sides and corners appear protected, but there is no bevel over the front edge of the phone. The front of the phone is actually slightly higher than the sides of the case. If you set the case front side down, it will be resting entirely on the front glass. The case does come with one clear film screen protector, however it’s rather generic, and although it applies easily without any bubbles, I just couldn’t get the bottom left to “adhere” to the glass leaving that corner wanting to peal up. I’ll probably replace it with a better quality screen protector. If you tend to be hard on your iPhone, or are all “thumbs”, then this probably isn’t the case for you, as it doesn’t offer the level of protection of many other cases. However, if you want a very slim, stylish case that really does compliment the look of the iPhone, and you are OK with the modest protection this case provides, then you may want to consider the iSkin aura.
