The Hybrid Autospinner Quartz Banger: The 80mm Hybrid autospinner quartz banger features a dual chamber, with dual spinner inlets in the lower chamber and a thick 8mm round bottom - it basically keeps heat trapped in the lower chamber while your bead spins rapidly ensuring maximum vaporization. A "full option" Banger if you will. Specs: Banger Type: 20 X 80mm Hybrid Autospinner dual chamber round bottom Quartz Banger. Joint: 14mm male 90 degrees / 10mm male 80 degrees Recommended Bead/Pillar type: beads 6 to 8mm or quartz pills and/or small shaped pillars. Recommended Carb cap type: Marbles x 2 (22/20mm + 14/12mm) Maintenance & cleaning recommendations: Avoid torching/heating over 650F/343C. Do not knock around and tap on solid surfaces. Always put down gently to avoid chipping/breaking, preferably onto softer surfaces once the banger has cooled to room temp. For deep-clean make sure items are at room temp, leave in 99% alcohol for 2 to 3 hours, remove, rinse with warm water and pat dry then leave outside to dry naturally (particularly) if the item has any kind of inlet holes in it.
