Pros
- Best-in-class flavor reference thanks to glass vapor path
- True on-demand response, heats only during the draw
- Very material-efficient — ideal for microdosing
- Removable battery, full charge
- Premium magnesium chassis, compact
Cons
- Highly dependent on draw technique, noticeable learning curve
- Chamber must be stirred for full extraction
- Modest battery life (approximately 5 to 6 bowls)
- Delivers fine flavor rather than large clouds
Temperature Settings for the Firefly 2+. You can find the complete overview on the main page.
Temperature Settings
The Firefly app (iOS and Android) allows stepless temperature adjustment between 150 and 260 °C. The device itself has no temperature display - only colored LEDs indicate charge level and ready status. For full control, the app is recommended, though after a while you'll find your favorite temperature and rarely need to change it.
Temperature tips: 175-195 °C works best for herbs - most terpenes unfold here. Above 200 °C, vapor gets denser but flavor diminishes. For concentrates (with the optional pad), 230-260 °C is recommended. The app also supports profiles for different temperature settings, which is handy when switching between herbs and concentrates.

Firefly 2+ Guides & Niches
The heater activates only when you draw and shuts off between pulls. This saves material and preserves flavor because herbs aren't constantly heated.
About 3-5 seconds from touching the sensors. This makes it one of the fastest convection portables available.
Place both thumbs on the side sensors simultaneously. The heater starts instantly. Releasing stops the heating. No material is wasted between draws.
The borosilicate glass chamber holds about 0.1-0.15 g of finely ground herbs. Don't pack too tightly — air needs to flow through.
Yes, with the concentrate pad. Place it in the chamber and set the temperature to 230-260 °C.
For precise temperature control, yes. The device has no temperature display, only colored status LEDs. The app is free for iOS and Android.
The 770 mAh battery provides about 30-40 draws or 4-6 bowls. A duration for a complete charge is not documented.
Yes, a WPA with 14 mm joint is available as an accessory. It replaces the standard lid and fits regular bongs and bubblers.
Remove the lid, wipe the glass chamber with a cotton swab and isopropanol (90%+). Do a thorough deep clean every 10-15 sessions.
Somewhat. The draw technique takes practice — slow, steady 10-15 second pulls work best. If you expect thick clouds immediately, you may be disappointed at first. Flavor-wise, it excels.
