OtterBox has long been know as the leader in "ultimate protection" for mobile devices. Their Commuter series cases are one of the top selling, and for good reason. The Commuter provides great protection for your device, giving you a step up from standard hard cases by using a skin/hard plastic combination. The Commuter is a mix of both the Impact and Defender series cases from OtterBox, combing the best of both worlds. The case fits extremely well, and completely covers the sides and back of the device. If you're looking to step up the protection on your BlackBerry, the Commuter may be just the thing for you.
