Clear case lets the device shine itself. It does not make the phone to feel bulkier, but adds additional grip. I do feel that the phone is more securely in my hand.
The raised corner edges are what do the main protection and it is what protects the screen on drops. The case is reasonably thick, but not thin at all. It seems thick, but does not feel like that.
It would have prevented the screen change from the drop I had before I bought this case. I am sure. Be smarter and buy before dropping your phone!
