RAM's most popular device holder - the X-Grip - comes in a variety of sizes to suit your iPhone, Samsung phone, or basically any other phone, phablet, or tablet. The spring-loaded cradle expands and contracts when squeezed on the side, to provide a perfect fit for your device. Since it is spring-loaded, it is constantly applying pressure to the sides of your device, to keep it secure. Buttons and ports on your devices remain accessible, due to the open design of the X-Grip.
