Advantages: Fits perfectly on motorcycle G 4G. Good material quality. Magnetized, allowing the sleep to close the valve. Disadvantages: The valve is very thick, and thus significantly increases the thickness of the phone. (Can be an advantage when falling!?) The magnet is very powerful, allowing to keep the valve closed when dropped, but I do not know if it is very good for the internal components? What is certain is that the compass will be unusable with this cover.
