The title may be a bit of a mislead, as I do not know anything about demolition, however this case may just do the trick in protecting your phone against any bangs, bumps, bruises, and scrapes. This was my first case from Trident Case that I bought for my HTC Evo 4G. I have to say I was blown away by the quality. While the case itself was very light, once you put your phone inside, you can really feel the heft. The case comes in two parts, a hard shell (that has a built in screen protector), and the rubber case. The case itself is cut precisely to the Evo's shape, no holes on the case covers any speakers, or screen itself. The rubber is hard, and doesn't tear easily even after heavy usage. I used this case for a good half year before I switched to the Cyclops, which is another series case from Trident. I used it daily, taking the case on and off whenever I had to swap batteries and it's held up regardless of what I did to it. It's a great case to consider when you want to keep your Evo 4G safe.
