about this project PERFECT BACKSEAT ENTERTAINMENT: This car headrest mount is specially designed for car headrests to keep your kids or other backseat passengers entertained during long drives. Perfect for rear passengers watching movies, reading e-books, playing games and more on road trips. Easy to Install and Use: This car mount is easy to install. There are two screws and a ball joint on it. Screw twist lock design allows you to install and adjust it without any tools. Note: Please carefully measure the distance between the two headrest rods and the diameter of the headrest rod before purchasing. SAFE AND STABLE: The car tablet holder features stabilizing arms to effectively support large-screen devices like iPads, making it a convenient way to hold most 14-inch tablets. Speed bumps do not affect the screen. 360 Degree Rotation & Stretchable: The headrest tablet holder provides 360 degree rotation. You can enjoy your tablet and phone in portrait or landscape mode. You can also adjust the retractable stand and find the right distance and angle to view the screen. Wide Compatibility: This car headrest mount is suitable for tablets, mobile phones and other devices from 5 inches to 14 inches, so it covers a variety of mobile devices sold in the market today. Spring-loaded, the stand will grip the device tightly and won't move easily. Intentionally designed holes allow the device to still charge while clipped to the car's headrest mount.
