Powerful Magnetic: Four-piece-magnet provides an intensive force of attraction which helps your phone stop swaying or falling. The magnet is strong, but no communication interference.
Steady Mount Design: Two-size-clip design mount helps it steady enough to stay attached to the louver and protect your device from swinging up and down no matter how bumpy the road is.
Special Protection Concern: Two protection films are extra for your installation which protects your phones from adhesive residue and makes it easier to remove the plate. Extra film, particular concern.
