Using your Black Mica Wide Hand Shower is easy. First, connect the 1500mm hose to your shower system. Then, adjust the tilt function to get the perfect spray angle for your needs. When showering, enjoy the wide spray coverage for a more relaxing experience. As for maintenance, regularly clean the shower head to prevent blockages. You can soak it in vinegar to remove any mineral deposits. Also, make sure to check the hose for any signs of wear and tear. If you have any issues, refer to the Warranty Guide. Remember to keep the water pressure within a reasonable range to avoid damaging the shower head.
