This case has defender quality strength with the added benefit of being fully waterproof. Much slimmer than the Armor series and much easier to get the case in and out. The build quality on this case is far superior to the Lifeproof Fre cases as the plastic on the frame and screen on Lifeproof's cases seem cheap. This case is very durable and the sound quality when sealed is great. I would highly recommend this case over for any one looking for full waterproof protection in a durable, sleek design.
