I just received my Rugged add on pack for my Seidio Innocase Surface case for iPhone 4. The Rugged is Seidio's answer to the Otterbox Defender, except that the inner most case is their standard Innocase Surface (a slider case). The concept is one system that can be used when needing minimal protection (just the inner slider case), or when maximum protection is needed (adding the outer layer plus hard plastic exoskeleton). Quick summation...I like this case. It's a bit thicker than the Otterbox Defender, but on the other hand, it doesn't always have to be that thick. Pop the exoskeleton and the outer thick silicone off, and you're back down to a slider case. I'd say that this case is even more drop protection than that of the Defender, which is already way overkill as far as drop protection goes. In other words, with either case, I don't know of a drop that they couldn't sustain. Pros: -I really like the camera protecting flap that is on the case, and how it pins back when needing to take a pic. The only downside to that is that now, to use the flash as a flashlight, it's not as quick as just unlocking your phone and hitting your flashlight app. You'll also have to undo the cover as well. -Amazing holster with this case! Very sturdy feeling, great clip in mechanism, and it also has a slide lock to keep the latch from accidentally releasing. As a bonus, the Otterbox Defender also fits in it perfectly (I hate the Defender holster) -Not as much silicone exposed on the exterior of the case as the Defender. I love that the plastic exoskeleton covers most of the back of the device. I hate that the entire exterior of the Defender is silicone, as it attracts lint like crazy. Cons: -I'm not quite as big of a fan of this case's integrated port covers as I am those of the Defender, but they should still do the job of keeping any dirt, dust, or grit out of the headphone jack and dock connector. -The vibrate switch is REALLY recessed! You are basically reaching through 2 cases to get to it. It's not too deep for me to get at, but for someone who keeps their nails cut very short, or has bigger fingers, it could pose a problem to get at. Back View: With camera flap locked back: Front view: Deep vibrate switch cut-out: Compared to the Otterbox Defender: Holster: Holster locking mechanism: Otterbox Defender fitting perfectly in Rugged holster!: Nicest feature of this case/system...with the removal of the exoskeleton and silicone (about 10 seconds to do), this is what you're left with: By default, the inner case is black. If you order the Innocase seperately, as well as the Rugged add-on pack, you can pick any color Innocase you want (I chose green, obviously).
