Got the armor case for my Galaxy S3, had a few minor drops the first week it was on the phone, the second week while I was at work I dropped the phone off of a 70 ft. platform, only resulting in a minor scuff on the back. The cons I've seen about hard to hear or be heard are easily fixed, at least with the Galaxy, open the charging port and hit the extra volume button on the screen and it's just the same as if the case wasn't there. I've had the case a month now and it's seen quite a few falls and been exposed to tons of rain and it's held up perfectly. It also survived my washing machine.
Pros: High quality, Durable, survived 70 ft. drop, survived washing machine
