The "WD Edelstahl HMD" HMD is a cost-effective alternative to expensive HMDs like those from Zeppelin or Kaloud, for example. Made entirely of stainless steel, the tray provides excellent heat retention and distribution. The underside is heavily textured, slightly recessed, and equipped with many holes. This ensures optimal stability of the tray and airflow even with intense setups. As a result, the heat is evenly distributed on the tobacco. Cleaning is remarkably simple – just scrub the underside of the Edelstahl HMD with a wire brush.
