I had an iPhone before the Moto X, still trying to get used to it! I bought a defender series case because I had one on my iPhone and loved it, it protected the phone from frequent drops, screen getting scratched and allowing dirt to get inside (for a while, anyway, it always finds its way in!). This case is similar but it doesn't seem as sturdy as the iPhone case was, it's a little slimmer (not as bulky), which is nice, but it doesn't see like it would protect the phone from drops as well. Also, stuff gets inside ALL the time and I can't stand a dirty screen, so I'm always having to open it to clean it. But that may not be the design's fault, it has to have an extra opening near the bottom of the screen for a little hole (the microphone, I think). But it's annoying to have to open it a few times a week to clean it. With my iPhone, I had to open it to clean it maybe once a month. Every time you open it, the rubber part gets more and more stretched out and the protective plugs to fit in the same/correctly anymore.
Pros: High quality, Durable, slim design
Cons: dirt gets inside too easily, case hard to open
