Quick Verdict
Both the Convector XL V2 and the Sticky Brick Junior are genuine butane convection vaporizers that can produce exceptional vapor — but they go about it in fundamentally different ways. The Convector XL V2 is the more consistent, more repeatable performer with a precision-machined titanium body and a large heater matrix that delivers even extraction across the bowl with minimal technique required. The Sticky Brick Junior is a beautifully raw, tactile device that rewards patient users willing to dial in torch angle and flame duration, but punishes impatience with scorched hits. If you want the best convection vapor for the least effort at this price point, the Convector XL V2 wins. If you want a meditative ritual and don't mind the learning curve, the Sticky Brick Junior is a legitimate rival.
Camouflet Convector XL V2 Overview
The Convector XL V2 is a handheld butane convection vaporizer built entirely from aerospace-grade titanium. It uses a single-flame butane torch — the kind you'd find in any smoke shop — and a large internal heater matrix that acts as a thermal conversion chamber. When you apply flame to the intake port and draw, the butane heat is transferred through that matrix and delivered to the herb as pure convection airflow. The herb itself never contacts the flame or a directly heated surface, which is the defining feature of true convection design.
The bowl is accessed through a 14mm glass stem, which both filters and cools vapor before it reaches your lips. The XL in the name means it: the heater matrix is substantially larger than first-generation Convector units, which translates to greater thermal mass and a wider, more even heat distribution across the full diameter of a packed bowl. Heat-up is essentially zero — you apply the torch, you draw. There's no waiting, no app, no battery to charge.
Build quality is immediately apparent in the hand. The titanium body is machined to tight tolerances, feels dense and serious, and shows no flex or rattle anywhere. The airpath is entirely through glass and titanium — no plastics, no silicone in the vapor stream. Draw resistance is low to moderate and very consistent between sessions. Because the heater matrix has meaningful thermal mass, it stabilizes the heat delivered per draw in a way that a direct flame-to-glass design doesn't.
What makes the Convector XL V2 distinctive is that combination: the repeatability of a large heater matrix plus the zero-battery convenience of butane, in a body that is genuinely built to last decades. At $149, it sits at the upper edge of the mid-range, but the materials justify it.
Sticky Brick Junior Overview
The Sticky Brick Junior is the compact entry point into the Sticky Brick Labs lineup, and it's earned a devoted following for good reason. The body is hand-finished hardwood — typically walnut, cherry, or maple depending on the run — fitted with borosilicate glass components for the intake tube, bowl, and mouthpiece. It's a beautiful object in a way that precision-machined metal simply isn't, and for a segment of users that matters a great deal.
The heating mechanism is direct: you hold a torch flame at the glass intake tube's opening and draw simultaneously. The flame is pulled into the device by your inhalation, heating the air as it passes over the herb. Done correctly, this produces immediate, rich convection vapor. The design is brilliantly simple — no moving parts, nothing electronic, nothing that can break in any conventional sense other than the glass components.
The Sticky Brick Junior has a shorter airpath than the full-size Sticky Brick, which makes it more portable and more efficient per draw, but also less forgiving. The glass intake tube is unobstructed, meaning the flame-to-herb distance is relatively short, and torch positioning is critical. Too close, too long, or at the wrong angle and you'll combust or at minimum scorch the outer edges of your bowl unevenly. Experienced users develop the right touch; new users often don't, at least not immediately.
Draw resistance on the Sticky Brick Junior is very low — almost no restriction — which produces large vapor volumes quickly but requires an active, conscious draw speed to manage temperature. Vapor can be very hot straight from the device and benefits from the optional water piece adapter. At approximately $115, it undercuts the Convector XL V2 by $34 and offers genuine performance for that price, provided you're willing to invest time in technique.
Head-to-Head: Vapor Quality
This is the heart of any convection comparison, and here both devices genuinely perform — which makes the differences meaningful rather than catastrophic.
The Convector XL V2 produces vapor that is consistently rich in terpene expression from the first draw through the last. The large heater matrix distributes heat evenly across the bowl's full cross-section, which means you get complete, even extraction without hot spots. The first draw is noticeably terp-forward — cool to moderate temperature, highly flavored, clean on the throat. Subsequent draws build vapor density as the bowl comes fully up to temperature. Spent material comes out an even, uniform tan-to-light-brown across the entire bowl face, which is the physical proof of even convection extraction. You're not finding a ring of dark material at the edges with an underdone center, which is common in less even designs.
The Sticky Brick Junior, when dialed in correctly, can match that terpene expression hit-for-hit. Users who've spent time with it describe first draws as explosively flavorful — the immediacy of direct flame-heated air can deliver a thermal spike that extracts volatiles very efficiently. The problem is the qualifier "when dialed in correctly." Extraction evenness is heavily dependent on torch angle, flame size, and draw speed. An uneven torch hold produces a pronounced hot zone on one side of the bowl, which means some material is over-extracted while the opposite side is under-extracted. Stirring between draws compensates, but it's an additional step the Convector XL V2 never requires.
Vapor temperature at the mouthpiece is another meaningful difference. The titanium body and glass stem of the Convector XL V2 provide passive cooling through thermal mass and path length — draws arrive at a comfortable, moderate temperature. The Sticky Brick Junior's shorter airpath delivers hotter vapor that benefits from either a slow, deliberate draw technique or the addition of a water piece. Neither is a dealbreaker, but the Convector XL V2 is more immediately comfortable for direct inhale without modification.
Edge: Convector XL V2, for consistency and extraction evenness. The Sticky Brick Junior's peak performance is comparable, but its floor is lower.
Head-to-Head: Build Quality and Materials
These two devices represent genuinely different philosophies about what "quality" means, and both are defensible.
The Convector XL V2 is built from aerospace-grade titanium throughout. Titanium is chemically inert, corrosion-proof, lighter than steel, and essentially indestructible under any conditions a vaporizer will encounter. The machining tolerances are tight — no wobble, no slop, no cosmetic gaps. The 14mm glass stem is the only fragile component, and it's a standardized piece that can be sourced easily if broken. If you drop this device on concrete, you're picking it up and continuing your session. The all-metal and glass airpath means there is nothing in the vapor stream that can off-gas, degrade, or develop residue-related flavor contamination over time.
The Sticky Brick Junior's hardwood body is a different kind of premium. The wood is genuinely beautiful, and Sticky Brick Labs' finishing work is careful and consistent. However, wood is hygroscopic, can crack in extreme temperature swings, and will develop a patina — sometimes desirably, sometimes not — with use. The borosilicate glass components are the device's Achilles heel: the intake tube, bowl, and mouthpiece are all breakable, and replacements are an ongoing ownership cost. The glass-to-wood fit is managed through rubber gaskets, which are not in the vapor path but are in the airpath and require occasional replacement. Dropping a Sticky Brick Junior is a meaningful risk in a way that dropping a titanium device simply isn't.
Neither build is objectively wrong for its intended user. If you treat your devices carefully and value the warmth and craft of a hand-finished wooden object, the Sticky Brick Junior's build is genuinely lovely. If you want something you can throw in a bag, forget about for six months, and pick up again without concern, the Convector XL V2 is in a different durability class.
Edge: Convector XL V2, on objective durability and longevity. The Sticky Brick Junior wins on aesthetics and character.
Head-to-Head: Ease of Use
This category separates the two devices most clearly, and it's where the Sticky Brick Junior's otherwise genuine strengths become conditional.
The Convector XL V2 operates with a short, reliable technique: grind, pack the bowl, apply torch to intake port, draw. The heater matrix's thermal mass smooths out minor variations in torch distance and flame duration, making consistent results achievable quickly — even for users new to butane convection. Draw resistance is predictable and consistent across sessions and across users. There is no torch angle to optimize, no flame size to calibrate carefully. Point, heat, inhale.
The Sticky Brick Junior has a real learning curve that the community openly acknowledges. Optimal torch positioning is typically about 1–2cm from the intake opening at a slight angle, using a single-flame torch on a moderate setting. Too much flame overwhelms the airflow and combusts material. Too little or too far away and you get thin, under-extracted vapor. Draw speed is also a live variable — slower draws pull more heat across the herb and raise temperature; faster draws lower it. This is actually a feature for experienced users who want active temperature control within a single session without adjusting any hardware. But for a user coming from a desktop or electronic device, it can feel frustratingly inconsistent in the first weeks of ownership.
Loading and cleaning are comparable between the two. The Sticky Brick Junior's bowl is small and efficient; the Convector XL V2's 14mm bowl accommodates a range of load sizes. Both clean reasonably with isopropyl alcohol on the glass components; the titanium body of the Convector XL V2 is essentially maintenance-free beyond that.
Edge: Convector XL V2, significantly. The Sticky Brick Junior is genuinely rewarding once mastered, but the mastery requirement is a real barrier.
Head-to-Head: Value for Money
At $115, the Sticky Brick Junior is $34 cheaper than the Convector XL V2 — a meaningful gap at this price tier. For a user who masters the technique and takes care of the glass, that $115 can buy an exceptional convection experience. The core design is elegant and the vapor quality ceiling is high. The ongoing cost of replacement glass is real but infrequent for careful users.
The Convector XL V2 at $149 is more expensive upfront, but the titanium construction genuinely shifts the value equation over time. There are no fragile components to replace, no gaskets to monitor, no technique-dependent failure modes that result in wasted material. The consistency means less herb is wasted on under or over-extracted hits while dialing in. For users who calculate value across a multi-year ownership period rather than at point of purchase, the Convector XL V2 likely comes out ahead.
It's also worth noting that the Convector XL V2's performance is accessible from day one, while the Sticky Brick Junior's value — its high performance ceiling — requires time investment to reach. That time has a cost too, particularly for users buying their first or second butane convection device.
Edge: Convector XL V2 over time. Sticky Brick Junior wins on initial outlay and for experienced users who already know how to handle a torch convection device.
Who Should Buy the Convector XL V2
- Users who want consistent, repeatable convection vapor without a steep technique curve. The heater matrix does the work of stabilizing heat delivery so you don't have to.
- Anyone prioritizing build longevity. Titanium construction means this device will outlast most of the vaporizers in your collection.
- Users who draw on the go, in varied conditions. The all-metal body is impervious to drops, moisture, and temperature variation in a way wood and glass are not.
- Those who value a clean, inert airpath. Titanium and borosilicate glass produce no off-flavors over time, even with heavy use.
- Experienced convection users who want the best even extraction at this price point and are tired of stirring bowls mid-session.
Who Should Buy the Sticky Brick Junior
- Experienced butane convection users who already understand torch technique and want a raw, high-ceiling performance device.
- Users who value tactile ritual and craft aesthetics. The Sticky Brick Junior is a genuinely beautiful object that the Convector XL V2, for all its engineering, isn't designed to be.
- Budget-conscious buyers who are prepared to invest time in technique rather than money in a higher-priced device.
- Collectors and hobbyists who enjoy the active, engaged nature of torch convection as a practice rather than a means to an end.
- Users who pair their device with a water piece regularly — the Sticky Brick Junior's very low draw resistance and hot vapor are well-suited to a bubbler, which also addresses its main comfort limitation.
