Using your Quad Lock case for iPhone 11 is a breeze. To attach the phone to the mount, just align the case with the mount and use the dual - stage lock. It'll snap into place quickly. When you want to remove it, simply use the same lock mechanism. It's all about technique, not brute force. As for care, you can wipe the case with a soft, dry cloth. Avoid using harsh chemicals as they might damage the polycarbonate core or the TPU outer shell. Also, make sure to keep the case clean from dust and debris, especially around the lock area, to ensure smooth operation. This case is wireless - charging friendly, so you can charge your phone without removing it from the case. Just place it on a compatible wireless charger as you normally would.
