I love rugged cases and that is why I bought Urban Armor gear case for my Samsung Galaxy S4. This case is made of shock absorbing inner rubber layer. The mid shell is made of rigid plastic. Each corner of the case has thick rubber that protects the good-looking edges from corner drops.
Folks at urban armor gear offer four colors and they also included a screen protector in the package. It costs 35 dollars which falls in the same price range as Otterbox Defender and Spigen SGP Slim Armor case. Here is my video review of it.
If you ask me, the Urban Armor Gear Case is better than those two as it is much slimmer and has a taller tip than the Slim Armor case for Samsung Galaxy S4.
