Joking aside. For years I had a Nokia C7 and was impressed by the resilience. The Lumia 820 has this resilience also: Once, even without shell, I have beaten it out of my hand ... Flog 2 meters. The display opened metal, polycarbonate frame struck the wall. End of the story: The polycarbonate shell was healing. Scratches on the wall (!) And minor scratches on the display (which were removed Because of the coating problem even with a new glass).
The 820 has nunmal no Gorilla Glass, and the display glass is pretty exposed at the factory state! If one cell phone on the table, the glass is right on - and scratched. Or you hit sichs like me out of your hand.
That's why -> Durable Case in green (because green is my favorite color;)).
The case is in my opinion really good. It's as good as a mindestes Bumper and it makes the phone no thicker than a Galaxy S3 with Bumper. It is also just as hard. The camera is protected, the display edged in rubber. Who still has concerns, I recommend a film. Actually 5 stars if a gap at the camera aperture would not. However, this is halbsowild. Something in my opinion is production engineering rid conditioned and quite heavy. I would order it to me and try.
I also uploaded any pictures to show how the green looks and which gap is present on the camera.
So if you are also such problems with the Lumia have, or even standing in front of a display for negligent use of Nokia, then I recommend the Case!
