I am a long term Otterbox user. This is my 8th device to receive this protection. I usually purchase the Commuter Series for my wife, the Defender for myself and my children. We are much harder on our devices than she is. All of the Defender cases to date have had a very strong holster, making the weak point the belt clip. Something however went really wrong with the S4 holster. I've had my case for just about a month and have just filed for my 2nd warranty request for a replacement holster. The bottom clips that hold the phone keep breaking off. Additionally it appears that he phone can only go in one way if not it falls out.....this is very unusual from my past cases S3, Atrix, Atrix HD, HTC OneX, you get the idea. That being said the case itself has protected my S4 non-stop when it has fallen out of the holster because I am too thick in the head sometimes to realize that it is not secure. Additionally when it has been thrown by my 2 year old Grand Daughter. Either way this is a great case who needs a little redesign for the holster.
Pros: Durable, high level of protection for device
