The attachment "FCS® Fyre Stainless Steel HMD" is a cost-effective alternative to the expensive HMD's from e.g. Zeppelin or Kaloud. The attachment, made entirely of stainless steel, brings with it the best heat storage and distribution. The underside is heavily roughened, slightly lowered and has many holes. This ensures optimal hold of the attachment and draft even with heavy contact setups! The heat is distributed very evenly over the tobacco. Cleaning is very easy - simply "scrub" the underside of the stainless steel HDM clean with a wire brush.
