Got an Otterbox Defender in the mail yesterday (my phone comes in on Monday). I was a bit disappointed with the case after thoroughly inspecting it. Here are my thoughts:
Pros: It's a good looking case on the outside.
Cons: It only comes in one color (the black looks good an all, but some variety would be great)
It is difficult to open the case to insert/retrieve the phone (although I have figured out that if you use your thumb on one of the arrows and forefinger on it's counterpart, a gentle press will help it open)
The inner plastic case seems very flimsy and I see it breaking fairly easily after a bit of use.
The buttons feel very stiff, now I'll admit I didn't give it a fair shake because I didn't have the phone to fully try out the buttons on it
Overall: Looks good, but I don't see this case lasting long in my hands. It got packed up this morning and is in the mail for a return. Not sure what I'll go with, but it won't be the Defender.
Note: I have had several Otterboxes on my phones before and they were all much tougher and better constructed than this model.
