If your draw feels off, here are quick fixes:

• Too tight: Open the airflow ring fully. If it's already open, clean the holes.
• Too loose: Close the ring partially. If that doesn't help, check for a cracked mouthpiece.
• Inconsistent draw: The ring might be stuck in a wrong position. Clean and rotate it.
• No airflow at all: Check if the mouthpiece is blocked or if the device is assembled incorrectly.

If you've tried these and still have issues, it might be time for a new device or professional service. Don't try to disassemble anything yourself unless you know what you're doing.
