Flowermate WIX

The WIX puts concentrate straight onto a ceramic coil sitting in a borosilicate cup, and whatever does not vaporise either bakes onto that glass or condenses a centimetre higher in the mouthpiece screen. Flowermate's quick guide is blunt about the remedy: clean daily, right after use, because a warm unit gives up residue that a cold one will not.

1. Work on it while it is still warm: The manual names this as the easiest way to lift residue, so do it once the session ends rather than the next morning.

2. Pull the zirconia mouthpiece off: It lifts straight up off the atomizer on a friction fit, no thread involved. Three black O-rings ship in the kit, and a mouthpiece that has gone loose or leaky wants a fresh one.

3. Swab the atomizer and mouthpiece: Flowermate specifies a cotton swab with isopropyl alcohol, 91% for preference. Keep the swab damp rather than dripping. The coil wires down to the 510 base directly beneath the glass, and the manual warns against pouring anything into the unit or opening it.

4. Soak only the mouthpiece: It is the single part cleared for submersion, and even then for no more than ten minutes in isopropyl. The battery body must never go in liquid, and the same applies to the atomizer assembly.

5. Change the mouthpiece screen with the clean stick: Push the stick in through the top hole of the mouthpiece to drive the screen module out of the bottom, lift the mesh off the white silicone carrier, fit one of the three stainless screens from the kit, then press the module home with the same stick. Swap the screen once the draw stays tight after a wipe.

6. Keep the air vent, button and USB-C port dry: Wipe the outside of the battery with a dry or barely damp cloth and keep alcohol well clear of those openings.

7. Replace the atomizer rather than rebuild it: It unscrews from the 510 battery, and spares sell separately in packs of five, each a borosilicate cup with its own ceramic coil. That same thread takes a standard 510 cartridge if you would rather run one, though none is included.

Output is capped at fifteen seconds per press, so let the button go between hits. Five red flashes mean the cell is flat, and charging works while you vape. Flowermate's two year warranty excludes the battery.
