The ElementCase Vapor4 for the iPhone 4 is getting a whole lot of buzz. So much so that the ElementCase website states the following: "You may be experiencing problems due to the excessive amount of traffic on our site." Whoa.

What makes the ElementCase Vapor4 so popular? Firstly, it's made with aircraft-grade aluminum, which is lightweight but hella strong. The Vapor4 is screwed on with a hex key and offers the utmost protection -- in style.
