Overall this is a pretty good case. I had a Defender on my iPhone 4s so I naturally bought one when I upgraded to a 5s. It offers pretty good overall protection in regards to impacts and normal wear and tear. The one real drawback is the opening for the home button/fingerprint reader. The screen protector goes around it but does not cover it. It is just a hole cut out of the screen protector. This hole allows dirt particals and dust into it and onto your screen. I have had this phone and case for maybe 2 weeks and I amalready gettign little marks on my screen and the screen protector around this opening. I have a feeling I am going to have to keep taking this case apart (and wear out the silicone covering) every couple weeks to keep my screen from getting all scratched up. Kind of a bummer really. I need a case that will keep dust and dirt off of my phone better than this. Seems like a fairly obvious issue with a case of this caliber and price.
Overall, I love this case. It does add some bulk to the phone, but it protects very well from bumps and scratches. Dust protection is so/so as every time I take the case apart there is a fair amount of dust and dirt inside the case and it has scratched up certain parts of my phone. But I work outside, in the woods and probably put this case to test at the extreme end of what this case is designed for. My only real complaint is that the silicone cover is not very durable. I have had this case for about a year and a half now and I am on my fourth silicone cover. It keeps getting stretched out to point where it is unusable. The first few times it was stretching out at the corners to the point it would just about fall off when I took it out of my pocket. This last time it stretched out over the home button so much that it was difficult to hit that button. On a positive note, Otterbox has a fairly simply warranty and replacement poicy and has replaced the cover every time with no charge and no hassles. I give them a huge thumbs up for customer service.
