The MAXX "Guard" Heat Controller (HMD) features a stainless-steel construction with a titanium coating and Zidclouds' exclusive airflow technology, which reduces inhaled CO levels. It prevents coal and ash from entering the bowl and offers the fastest heating time of 3 minutes among all heat control devices. The protective lid secures the coals, preventing spills if the hookah is overturned. This all-in-one device eliminates the need for a wind cover and grid.
