VERSATILE This Universal Mounting Surface Cup Holder Adapter is perfect for all your mounting needs! It provides an ideal flat mounting space for almost ALL OEM windshield suction device mounts. The Cup Mount is also perfect for GPS, Smartphone, Tablet, Laser / Radar Detector, MP3 player, and other types of device mounts! SAFE & DISCREET Provide an extra level of safety and security for your vehicle by displaying your device in an area that is less visible to outsiders and more visible for you. A closer, more discreet mounting surface means no more squinting and less worrying about people tampering with your car. Having a mount-free windshield also provides more than just discretion, it also provides safety. Keeping your mount out of your direct line of vision ensures a clearer view of the road, which means less potentially illegal distractions, and a safer drive overall! EASY INSTALLATION Twist-to-Fit design utilizes an expanding weighted base to securely mount your device holder quickly and with more stability. The universal base adjusts to fit most cup holders from 2.5"-3.75" wide. Portable design does not require sticky pads or screws, which makes transporting your mounts and devices between cars incredibly easy!
