Overview
The Firefly 2+ (commonly abbreviated as FF2+) is a portable, battery-powered dry herb and concentrate vaporizer manufactured by Firefly Vapor, released in 2019. It is the third generation in the Firefly line, following the original Firefly (2013) and the Firefly 2 (2016). The Firefly 2+ uses a convection heating method with a borosilicate glass-lined oven, heating herb on demand when the user activates the touch sensors on the device's exterior. The unit features a distinctive lid design, removable rechargeable batteries, and app-based temperature control via Bluetooth.
The Firefly 2+ was positioned as an iterative refinement of the Firefly 2 rather than a complete redesign. As one knowledgeable community member documented, "The Firefly2+ is basically the same as the FF2, but it comes with an updated firmware package/app update to help heating and battery efficiency. But the biggest change was in the oven screen, which now has slightly more airflow than the FF2 screen." Firefly also offered an upgrade path for existing Firefly 2 owners, who could send their units to the manufacturer to receive the new screen and firmware update.

Community Reception
The Firefly 2+ occupied a complex position in the community's regard. It was recognized as a device capable of producing excellent flavor, particularly at low temperatures with whole nugs or a chunky grind, and was appreciated for its on-demand convection heating, compact form factor, and glass-lined vapor path. Several community members kept it in their rotation alongside other vaporizers, and it was considered a viable option for users who valued flavor chasing and light, infrequent use.
Pros:
- Outstanding low-temperature flavor extraction, especially with whole nugs or coarse grind
- True on-demand convection heating — no wasted herb between draws
- Compact and discreet for portable use
- Dual-use capability with both dry herb and concentrates
- Ceramic and glass construction in the oven area
- App-controlled temperature precision
Cons:
- Stirring requirement was a significant and widely cited frustration; the bowl required frequent stirring between draws for even extraction, which many users found tedious and impractical, especially on the go
- Described as "pretty frustrating to use" beyond low-temperature flavor hits by one experienced community member
- Maintenance demands were considered above average
- The plastic mouthpiece was noted as incongruent with the otherwise premium materials
- Battery life was a recurring concern across Firefly generations
- Warranty and repair support restricted to US and Canada, creating significant problems for international customers
- The internal glass component (the heating element visible as the "round part that becomes red when the vape is heating") was fragile and could crack from even minor drops
- When seeking an on-demand portable replacement for other vaporizers, some users explicitly ruled out the Firefly 2+ due to the stirring requirement
The community widely agreed that the Firefly 2+ was a niche device — excellent for a specific use case (low-temp flavor sipping, light use, concentrate vaping) but not a versatile daily driver for most users.
Tips & Techniques
Loading
- Grind coarsely or use whole nugs for the best flavor results at low temperatures. One experienced community member specifically recommended "whole nugs or chunky grind on the low end" as the sweet spot for flavor.
- Do not overpack the oven; a loose load allows convection airflow to work properly.
- For concentrates, use the included concentrate pad placed in the oven.
Drawing Technique
- The Firefly 2+ activates via touch sensors on the exterior — press and hold both sensors to engage heating, then draw slowly and steadily.
- A slow, gentle draw encourages more even convection heating across the load.
- Stir between draws — this was universally acknowledged as necessary for even extraction. While frustrating, it is essential to avoid hot spots and underextracted portions of the bowl.
Concentrate Use
- One community member specifically praised the Firefly 2+ as "an outstanding portable concentrate vape," noting that it "can go up to 500° and when using it for concentrate you avoid a lot of the things that make it so annoying with flower, like the constant need for stirring and maintenance." Users seeking concentrate portability may find this to be the device's strongest use case.
Temperature Guide
The Firefly 2+ supports a wide temperature range adjustable through the companion app, up to 500°F (260°C).
| Temperature Range | Effect | Notes |
| Low (320–350°F / 160–177°C) | Maximum flavor, light effects, terpene-forward | Community-recommended sweet spot for flavor chasers; use with whole nugs or coarse grind |
| Medium (350–390°F / 177–199°C) | Balanced flavor and vapor production | Good middle ground for most users |
| High (390–430°F / 199–221°C) | Stronger effects, reduced flavor | Diminishing flavor returns; some users found higher temps produced harsher vapor |
| Max (430–500°F / 221–260°C) | Maximum extraction; concentrates | Primarily used for concentrate vaping; one user from the community comparing Firefly 1 and 2 noted that "the firefly 2 can get your herb a little hotter if you so desire, thus producing stronger results" but cautioned that "the higher heat makes stronger but harsher vapor" |
The community flavor chasers specifically gravitated toward the lowest usable temperatures, where the Firefly 2+'s convection design excelled.
Maintenance & Cleaning
- The oven screen was a key maintenance point. The updated FF2+ screen offered improved airflow over the FF2 version, but still required regular cleaning.
- The glass-lined oven should be kept clean for optimal flavor; residue buildup affects taste and performance.
- The vapor path (notably, not an all-glass path despite the glass oven liner — one knowledgeable community member pointed out that "Firefly does not" use a glass stem as the vapor path) should be cleaned regularly.
- ISO (isopropyl alcohol) and the included cleaning tools (brush and pick, if obtained separately since the FF2+ did not ship with these) are standard cleaning implements.
- Concentrate use requires cleaning of the pad and oven area, though community members noted this was less maintenance-intensive than flower use.
Common Issues & Fixes
Cracked Internal Glass
The most notable hardware failure reported involved the internal borosilicate glass component cracking after drops, even minor ones. One community member reported that after a light drop, "the inside glass (the round part that becomes red when the vape is heating) now is broken and a little piece of this glass came out. The vape started to work bad, less smoke and a really annoying whistle when I use it." This component is not user-replaceable and requires manufacturer service.
Warranty Limitations (International Users)
Firefly's warranty and repair service is limited to US and Canada addresses only, as disclosed on their official website. International customers who purchased through third-party retailers were not always made aware of this limitation. One community member from Italy found this particularly frustrating: "you are forced to send the product to them if it is broken" yet the company would not service international units. The community noted this was clearly stated on Firefly's own site, but agreed it was poorly communicated through authorized resellers.
Uneven Extraction
The need for frequent stirring was the most common usage complaint. Without stirring, portions of the bowl would remain underextracted while others could overheat.
Herb Particles in Mouth
Some users reported small herb particles entering the mouth during use. Community members suggested using mesh basket screens or water filtration to mitigate this issue, though the Firefly's design makes aftermarket screen additions less straightforward than with stem-based vaporizers.
Battery Life
Battery performance was a legacy concern across all Firefly generations. The FF2+ firmware update aimed to improve battery efficiency, and swappable batteries provided a partial mitigation (carry spares), though the FF2+ notably shipped without the spare battery that the FF2 had included.
Accessories & Modifications
- Concentrate Pads — Required for concentrate use; the FF2+ shipped with one pad (the FF2 had included two)
- Replacement Batteries — Removable and swappable; carrying spares was recommended given battery life concerns
- Travel Case — An official Firefly travel case was available (retailing around $29 new), praised by users who traveled with the device
- Charger — Proprietary charging dock included
- FF2 to FF2+ Upgrade — Firefly offered an official upgrade service where FF2 owners could send in their units to receive the new oven screen and firmware update, effectively converting them to FF2+ specification. Community members confirmed this service was functional, with at least one reporting that after the upgrade, Firefly confirmed the warranty was extended accordingly.
The Firefly 2+ did not use standard glass stems or water pipe adapters (WPAs), which limited its compatibility with the broader ecosystem of glass accessories favored by the community.
Comparisons
vs. Firefly 1 (Original Firefly, 2013)
A community member who owned both reported that "the vapor is about the same as long as you know how to use it properly. But the firefly 2 can get your herb a little hotter if you so desire, thus producing stronger results." The FF2/FF2+ was smaller, lighter, and had app control, but the original Firefly was remembered fondly for its distinctive "hot rod" aesthetic. Battery performance differences were considered minimal when using the same upgraded battery in the FF1.
vs. Arizer Solo II / Argo
Both the Firefly 2+ and Arizer portables were frequently mentioned together in discussions about clean vapor paths. The Arizer devices use glass stems and are session vaporizers, while the Firefly 2+ is on-demand. Users seeking portability for walks sometimes compared the Argo to the Firefly 2+, but the FF2+'s stirring requirement was a dealbreaker for that specific use case for some.
vs. TinyMight
In flavor comparisons, the TinyMight was widely regarded as superior for daily use. One experienced community member stated that the "Firefly2+ has some great flavor with whole nugs or chunky grind on the low end, but that is all it's good for, pretty frustrating to use otherwise," while praising the TinyMight as the clear leader for portable convection flavor across the full temperature range. The TinyMight offered both on-demand and session modes, glass stem compatibility, and WPA options.
vs. Tafée Bowle
Both were mentioned in flavor-chasing discussions. The Tafée Bowle was recommended as a convection alternative with fast heat-up and easy use, particularly for users who found the Firefly 2+'s maintenance and stirring requirements burdensome.
vs. Milaana
The Milaana was described as having "something special" in its flavor profile and was considered top-tier for portable convection flavor, similar to the Firefly 2+ at its best but without the same level of frustration in daily use.
For Concentrate Use
The Firefly 2+ found a stronger niche as a portable concentrate vaporizer than as a flower device in the eyes of some community members, with one specifically recommending it as "an outstanding portable concentrate vape" that avoided the stirring and maintenance issues that plagued its flower performance.
