The SM623-G cup holder car mount can be used with large smartphones up to 6.75” tall (8” screen size). This mount includes Arkon’s Slim-Grip Ultra Universal Smartphone and Midsize Tablet Holder, an adjustable cup holder mount with 5” flexible gooseneck, and optional adhesive support pads (for use with extra large cup holders). The Slim-Grip Ultra patented spring-loaded holder makes it easy to insert or remove the cell phone or tablet from the holder with one hand, yet it holds the device securely. The top and bottom adjustable-leg design of the Slim-Grip Ultra helps keep any side buttons and ports unobstructed, making it ideal for use with the side accessible buttons on the Samsung Galaxy S7 edge or Galaxy Note Edge. Included with the holder are 8 support legs (4 short and 4 longer versions) that can be customized based on device size. The recommended configuration for most smartphones and midsize tablets is to have 2 short legs on the top of the holder and 2 of the longer legs on the bottom of the holder. For larger devices, use all 4 long support legs. Bend the 5” cup holder mount’s aluminum gooseneck, loosen the wing nut to adjust the mount up to a 90° angle, and rotate the swivel ball adapter head for additional 360° rotation, giving you the ultimate flexibility in viewing the phone or tablet from any angle.
