This is the third phone mount I have had, the first one was rubbery and the phone bounced around, the second one was sturdy, but I had to take the case off the iPhone for it to fit securely. However, this one is a super-heavy duty phone mount that secures the phone and the case. The mount rests on a 'ball' that allows you to change the viewing angle. the side grips move in to grab the phone, and are released by pushing a small button on the back - making it easy to add and remove the phone. I give it 5 stars for ease of use and ruggedness.. highly recommend.
