I want to thank the folks from Rokform for sending me this case for review. They offer several other types of cases and colors for each model The model I reviewed was the Rokbed case for the iphone 4. It’s is a very strong and durable case. It comes pre-assembled from the factory. All that’s needed to install the case is simply gently slide the iphone into the case and put the bottom in place. The bottom plate is held in place by two screws. The screws are tightened with the torque tool provided that comes with the case from RokForm. Overall, I thought this was a very rugged case. The aluminum used to make this case is the same material used in many aircraft parts and automobiles. So if its strong enough to hold things like that I think it’s strong enough to protect my iPhone 4. Being an outdoorsman I really enjoyed having this color. There are several other colors that can be purchased on their website at http://www.rokform.com. Go check these cases out you won’t be disappointed. They also have an iPad case and desktop case for the iPhone that are awesome as well. Thanks for reading.
