Step 1. Read SPECTRUM fill state: empty hardware. A factory-filled flavor stick is not matching SPECTRUM.

Step 2. Read ceramic coil and 1.8 Ω. Do not copy a mesh ohm from an HQD listing onto this SKU. If the carton differs from the SPECTRUM table, the carton wins.

Step 3. Read 66 × 36 mm. Do not use an HQD lifestyle photo as a millimetre certificate. Thickness remains unknown.

Step 4. If you need a watt starting band from 1.8 Ω, use the WINDBAR wattage calculator on this site. Packaging wattage still wins. Do not open an off-site HQD shop.
