I have the first time a bought cheap because the very expensive brand bags were in my S3 always after a short time back. The vulnerability here are the two small plastic rods which lie at the keys. But only if you take it a lot out of his pocket. But even if one would break out the work the bag continues without limitation and I'm even surprised and will be 2 years to survive until the next phone the way it looks so far. I am totally satisfied!
