One of our all time favorite aluminum bumper cases for the iPhone 4 is back in our hands and ready to case the iPhone 4S with all of its might. E13ctron's S4 aluminum bumper case was one of a kind back when we first reviewed it last year combining two front and back pieces allowing for unique color customization that has become immensely popular ever since the S4's debut. Today we take a look at a new form of the S4 called the S4V Hybrid, as the name implies this is a hybrid aluminum bumper made from one part aluminum and one part Acetal to create a winning combination to help combat that dreadful reception blocking symptom that aluminum cases suffer from. Will the S4V Hybrid prove to be a better performer than its counterpart? We find out after the jump!
