Official bumper is overpriced and over rated..
It is overpriced but it's not over rated. I have 5 different cases, and the official bumper provides the best protection on the sides and has the most sensitive buttons. It is like you're actually pressing a button and not just mushing on the case. Also, it is the best looking bumper out there. But by no means is it perfect. Being a bumper it doesn't offer any protection for the back and the dark grey plastic part tends to bend and break at the bottom near the micro usb slot.
