The iSkin Solo case for the iPhone 4 is a straight forward simple yet good looking TPU case. The Solo is one of the better TPU (Thermoplastic) on the market, it doesn't feel like a cheap case and it's very well designed. The back of the Solo has a shiny glossy finish which shows fingerprints and a bit of lint if you pick a dark color. After using the Solo for a while I found that it can get scratched easily but it isn't all that noticeable.
You can see that the blue/aqua colored Solo has this really nice neon effect at certain angles which light up even more when you use your LED flash. Surprisingly enough that Solo does no affect and transfer color into images taken using the LED flash on the iPhone 4. To help you easily slip the Solo onto your iPhone 4, iSkin has made these two small slits at both the top corners that really help you get your iPhone 4 inside quickly. Because of these two slits, the top part of the Solo case above the sleep-wake button tends to lift up a little. This might bother you if your very picky so it's something worth noting. You can see how much of a lip the Solo has over the front screen which elevates your screen and prevents any surface contact should you place your iPhone 4 screen side down.
One of my favorite features about the Solo case is that all around the antenna band it a very grippy micro texture which really gives you a good grip of your iPhone 4. This texture is also located on the inside back part of the Solo which provides a matte frosty look to the back of your iPhone 4. This was probably also used to prevent any watermarking.
The Solo looks very sharp on the iPhone 4, it's design is very form fitting and slim. You're not going to have trouble slipping this in and out of your pocket. Buttons stay very responsive to every click but the cutout for the silent switch needs to be bigger as you will find yourself needing to use your fingernail to get to it.
I don't recommend going for the black colored Solo because it shows a lot of fingerprints and dust. Overall the Solo is a very decent quality case for the iPhone 4. iSkin uses high quality materials to make the Solo like adding Microban antimicrobial protection that also helps keep the case looking and smelling new for a long time. The Solo provides moderate protection to your iPhone 4, and if you're seeking some tough drop protection I would recommend going for iSkin's Revo4 case that we reviewed instead. You can pick up the Solo in five delicious colors. Price $29.99.
