How to Charge

2. Place the Firefly 2+ on the charging dock: the LED light blinks blue when charging and turns solid blue when fully charged.

How to Fill the chamber for the best results

View quick guides below for Loose Leaf or Concentrates or watch each video guide on Youtube!

How to Pack a Bowl of Loose Leaf

1. Remove the magnetic lid by lifting up on either side.

2. Use coarsely-ground material. The grind should be small and crumbled but not too fine. A powdery grind will cause pull-through.

3. Loosely fill the glass chamber slightly past the rim and tamp down gently.

4. Ensure the interior surfaces are completely free of debris for a tight seal.

5. Replace the lid and make sure it is seated correctly.
