I heard a lot about Otterbox phone cases so when I needed a case for my new iPhone 7 I decided to give Otterbox a try. I love that once encased with the Otterbox Defender, the iPhone is no longer slippery, has a nice feel to it, and is protected all around. My last iPhone suffered a nasty cracked screen so for the new case I made sure I have an extra layer to protect the screen. The Otterbox offers plenty of screen protection, in addition to a hard plastic layer on the inside to protect the other five surfaces and a rubber layer on the outside to absorb shock as well as to provide a good grip. You can get yet an extra layer of protection from the belt clip, but from my past experience with belt clips for my Palm Pilot I am staying away from them. My last Palm Pilot fell off my belt and I actually ran over it my own car. It was a long time ago, at least in computer age, but I still remember the pain. A nice touch with the Otterbox case's belt clip is that it can double as a stand for watching videos. Just not worth the risk for me, though, based on my personal experience.
It would be nice if the outside packaging of the Otterbox Defender shows how the case is assembled onto the iPhone. Even after I opened up the package, I couldn't figure out how to take the case apart to get the different pieces around the phone. The simple diagram with no words may work across different cultures but it was not easy to interprete. Luckily in the pamphlet there is a URL to a video, where I finally learned that the rubbery outside layer can be peeled back to get to the hardcase inside.
The rubber outside layer has sealable opening but I wish the port to access the Lightning connection can be more forgiving. It is too eager to snap shut on its own and I always have to use two hands to insert the Lightning cable. It does not help that the opening just fit the Lightning port so if your cable is already slightly out of shape it'll get worse and worse.
One issue that greatly affects me, perhaps not so with other people, is that I recently fell in love with the Hootoo iPlugmate, a USB flash drive that has a Lightning male connector on one end and a USB connector on the other end. Plug the Lightning end into an iPhone and use the companion iPlugmate app to backup photos, movies, and phone contacts to the flash drive. Our phones go everywhere with us these days, it's important backup of the phone be as simple as possible. Unfortunately, with my iPhone enclosed in the Otterbox Defender, I had no way of connecting the Hootoo drive to the Otterbox case. See the attached photo. The extra thickness of the case makes the connection impossible. I had to buy a Lightning extension cable, for about $10, then all is good again. With the Otterbox being at about $60, with the extension cable, the cost of having the case is now actually $70. People have different ways to backup their phones (you do, right?) but if the Hootoo iPlugmate is your way, then be warned that by itself it won't work with the Otterbox without totally stripping the iPhone from the case..
I think the Otterbox Defender is good case for a good price. Setup can be easier out of the box but the online video can take care of any questions you may have. Port covers can be a little forgiving but again it is not a big deal. More serious, to some people, is the additional cost of getting a Lightning extension cable, if you rely on some flash drive solution like that of the Hootoo iPlugmate.
