One thing I really liked about the iPhone 5 was the thickness, so it was important to me to not buy a case that made it huge like the 4S. This bumper has been working great for a couple months, including frequent drops buy me.
I have no dent or dings in the back of my phone even without the protection offered by complete cases. I added an "Invisible Shield HD" to this bumper and feel my phone is well protected now, but still comfortable to throw in a pocket.
It normally takes me a near fortune to find my perfect case. I need protection, but don't want to sacrifice weight and size. If this sounds like you.....buy this bumper case. Get a screen shield, this bumper, and you are set. 99.9999% of drops land on a corner or side. Those that don't are still protected as a bumper is raised and protects the back and screen. Take it from a case "expert" this what you need if you don't want to transform your sleek new device into a brick. I just bought another. Oh wait....its $10......a steal!
I paid $14.99 for this before the price drop. It fits pretty well. Maybe just sliiiightly loose on the edges at times. But barely. Overall, offers good protection.
