Using your Quad Lock case for iPhone 11 Pro is easy. First, just slide your iPhone into the case. To attach it to the mount, line up the case with the mount and use a quick, smooth motion. Detaching is also simple; just follow the same technique in reverse. When using it in your daily activities, avoid using excessive force as the lock works best with the right technique. For maintenance, you can clean the case with a soft, dry cloth. Make sure to keep it away from sharp objects that could scratch the case. Also, since it's wireless - charging compatible, you don't need to remove the case for charging, but ensure there's no debris between the phone and the charger for a smooth charging experience.
