An installation absolutely no problem. I also bought a competing version of Survivor which allows me to give a comparative opinion. The Lifeproof and its competitor offers a touchdown optimal screen. Access to keys is very good too. However if the Survivor seems "padded" in case of impact and has a base to maintain the type photo frame, preference goes Lifeproof which has a shoulder strap, which matter less gum is more enjoyable, and ESPECIALLY the part camera is waterproof, which is absolutely not the case of Survivor. On the Survivor you have to open a hatch, while the Lifeproof there permanently sealed opening. Finally, the fuel effect (bit annoying when the power is on and therefore brighter) strongly present on the Survivor is virtually absent from Lifeproof model. So Lifeproof advantage a little more expensive (almost double). The Survivor is for shock, the daily handling, while the Lifeproof will be "fine", waterproof (at least for rain and wet hands, as to keep the team at the Calypso there are others means even if the ad speaks of prolonged immersion). The shoulder strap and port waterproof camera without the requirement to open a cap, and the lack of competition make Lifeproof THE ideal solution. As for NUUD model that leaves the screen of the iPad in the air, I think this is mind we always prefer to scratch a screen protector as the original. Advantage Fré model. And I say good hit, good brightness. ... In short, this is the model we have chosen for our company. Anyway, all these compliments are encouraging without freezing progress, for it seems such that the "hood, covering" features a magnet does not stick etc. For me the big advantage to protect its iPad is THE GETTING STARTED, we seized it without fear of breaking it, it becomes a tool and a jewel.
