The NuGuard is a protective silicone case for the iPhone 4 and 4S. Silicone cases are a dime a dozen these days. In every mall, there is a vender selling them for $15-20 a pop. NewerTech has a decent offering for only $6.79. The quality is on par with most cases out there. While I am not a fan of silicone cases in general, the only attractive thing about this case is the price. Check out the review below.
