Good but.....
I've loved my s7 stem/ case holder on my bike, and car, for 6 months. Sadly the rubber that grips the phoneis increasingly poorly fitted to the plastic case meaning that normal road wobbling was enough to throw my phone from its (very well locked and secure!) case and into the road during a cycle this weekend. It's going to be an expensive replacement phone so, as much as I love the Rokform case/ stem I just cannot recommend it at this time.
