PAX Flow Review: The Take That Comeback of Vaporisers
"Take That's comeback shouldn't have worked."
The Good
- Design-conscious users who want stealth without compromises
- PAX 3/Plus owners ready for a genuine upgrade
- People who value discretion over raw power
- The "I want something that doesn't look like medical equipment" crowd
The Bad
- Value hunters who do the price-per-performance maths
- Anyone who's sworn off PAX after previous disappointments
- Power users chasing Mighty+ or Venty-tier clouds
- People who don't want to pay premium for polish
The Hook: The Patience Era
Take That's comeback shouldn't have worked.
They were a 90s boyband. The one that wasn't the Spice Girls. Robbie Williams left and became actually cool while the rest of them...
didn't. When they announced a reunion in 2006—without Robbie—the reaction was brutal. "Desperate," people said.
"Embarrassing. Just accept your time has passed."
Then Patience dropped.
And it was... good. Genuinely good.
Not ironically good. Not "good for a nostalgia act." The kind of good that made Q Magazine call it "a masterstroke" and the critics who'd sharpened their knives quietly put them away. They sold out Wembley.
They won a Brit Award. They made people who'd written them off as a punchline admit they'd been wrong.
The PAX Flow is walking into the same arena.
After the PAX Plus landed with a thud—incremental upgrades, same restrictions, price that didn't match performance—the brand felt finished. The vaporiser community had moved on. The Mighty+ was still the benchmark.
The Venty raised the bar. And PAX? PAX became a punchline.
"Premium marketing, budget engineering," people said. "All style, no substance."
I said it too. Publicly. In conversations.
In recommendations. "PAX has lost the plot."
So when the Flow arrived, I expected nothing. Opened the box with my arms crossed. Loaded some Pink Runtz.
Took a draw.
Then I sat there for a minute, recalibrating.
Because this—this actually works.

Vapour Quality & The "Strain Test" 8.0/10
I loaded some Pink Runtz—candy-sweet hybrid, the kind of terpy dessert strain that rewards good extraction and punishes harsh devices. Set the Flow to 185°C via the app, waited 25 seconds, pulled.
The vapour is... good.
Not "good for a PAX." Not "better than expected." Actually good. The kind of vapour that makes you check the device in your hand because you're not sure this is the same brand that made the Plus.
The redesigned chamber is the difference. PAX finally figured out what everyone's been telling them for years: the original oven design choked the airflow. It was like trying to breathe through a blocked straw.
The Flow opens things up—like removing the restrictive exhaust from a motorcycle and suddenly discovering the power was always there. Same engine. Now it can actually breathe.
PAX claims six times more airflow than previous models, and for once, the marketing isn't lying.
At 185°C, the Pink Runtz came through sweet and fruity. Proper terp expression. Stepped to 195°C and the clouds thickened without losing flavour.
By 210°C, full extraction mode—roasty and satisfying in a way the Plus never managed.
The Comeback Test: I dug out an old PAX 3 from a drawer, loaded both with the same Pink Runtz, same grind, same pack weight. Back-to-back comparison. The Flow wasn't just better—it was embarrassingly better.
The difference in airflow alone justified PAX's existence for another product cycle. Like comparing Patience to "Pray"—both technically Take That, but one sounds like it was made by adults who've figured some things out.
The airflow still isn't Venty-open or TinyMight 2-effortless. It's not trying to be. This is a session sipper, designed for controlled draws and extended sessions rather than on-demand cannons.
The pull is comfortable now—not restrictive, not wide-open, just smooth enough that you stop thinking about technique and start thinking about the herb.
The flavour reality check: Those first 2-3 draws are spectacular. Proper terp expression, sweet and complex. By draw 5-6, it's fading.
By draw 10, you're in roasty territory. This is standard for conduction-heavy hybrids, but worth mentioning for flavour chasers expecting Solo 3 v2-level glass-path purity.
My mate Dave tried it after giving up on his old PAX 3 two years ago. His reaction: "Wait, when did PAX stop being rubbish?"
That's about right.

Design & Build 9.0/10
Sarah's reaction when she saw the Flow: "Is that the one you said was rubbish before?"
"Different model," I said.
"It looks the same."
"It's... different on the inside."
She raised an eyebrow. "That's what you said about the last one."
She's not wrong. PAX's design language hasn't changed—it's still that minimalist, polished-pebble aesthetic that made them famous. The Flow looks premium because it always has.
Anodised aluminium. Smooth curves. No visible screws or seams.
The kind of object that sits nicely on a desk and doesn't scream "VAPORISER" to houseguests.
The build quality is genuinely excellent. This isn't a box-ticker "premium feel" claim—the thing is solid in the hand, weighted properly, machined with the kind of precision that German engineers would approve of. At 107mm × 34.5mm × 29mm and 135g, it's noticeably larger than the Plus but still genuinely pocketable.
The matte finish resists fingerprints better than the glossy Plus. The button click is satisfying. It feels like a £255 device because it's engineered like one.
The side-loading oven: This is the real evolution. Instead of loading from the bottom like every previous PAX, you pop off a magnetic door on the side to access the chamber. Sounds small.
Changes everything. Loading transforms from a potentially fumbling disaster into something genuinely elegant. The magnetic door clicks into place with satisfying precision and hasn't come loose once during transport.
Heat management reality check: Here's where things get complicated. The relocated oven means the heat source is now right where your hand naturally grips. During longer sessions or when using Boost Mode, the Flow gets noticeably warm—not painful, but definitely warm enough that I've found myself shifting my grip or setting it down.
In Bong Mode (225°C)? It gets properly hot. After five or six minutes, I'm setting it down because holding it becomes uncomfortable.
PAX sells a grip sleeve for exactly this reason, but at £255, requiring additional accessories for comfortable high-temp use feels like an oversight.
Interior concerns: Some users have noted more plastic inside than expected for the price. The chamber itself is redesigned and improved, but the air path has components that feel more "gadget" than "tank." The stainless steel vapour path is a genuine improvement over aluminium, but this isn't German overengineering where every component feels machined from solid metal. It's PAX—design-forward, not durability-forward.
For stealth? For aesthetics? For "I want something that doesn't look like a power tool"?
The Flow delivers. Just don't expect it to survive being dropped down stairs.

Battery & Charging 7.5/10
The Flow finally has USB-C.
I'm going to let that sit there for a moment, because PAX users have been asking for this since USB-C became the standard. The proprietary magnetic charger is gone. You can charge your vape with the same cable as your phone, your laptop, your Switch.
Like normal people do.
Welcome to 2025, PAX.
Real-world battery performance: 4-6 sessions per charge, depending on temperature and session length. That's competitive with the Veazy, behind the Crafty+ (which manages 4-5), and well behind the Air MAX's swappable battery infinity. For an all-day-out scenario, you'll want to charge before you leave—this isn't quite "morning to midnight without thinking about it" territory, but it's solid.
The Spec Check: - USB-C: ✓ (finally) - Pass-through charging: ✓ - Replaceable battery: ✗ (sealed) - Charge time: 50% in 20 mins, 100% in ~40 mins
The fast charging is genuinely impressive. Twenty minutes plugged in while you're having dinner gives you enough juice for an evening session. This partly compensates for the modest battery capacity.
The sealed battery is standard for this tier, though it does mean you're looking at degradation in 18-24 months. No swappable 18650s like the Arizer lineup. That's the trade-off for the seamless design—no removable panels, no battery doors, no points of failure.
The device stays sleek; you just can't user-service it.
For daily use, the battery's fine. Not exceptional, not limiting. It'll get you through a work day.
It won't get you through a festival weekend without planning.

Ease of Use 8.5/10
One button. Haptic feedback. App for temperature control.
That's the Flow interface.
Long press to turn on. Wait 25 seconds. Haptics buzz when it's ready.
Inhale. Short press to cycle modes. Long press to turn off.
The end.
If you've used any PAX device, you already know how this works. If you haven't, you'll figure it out in one session.
The five heat modes: 1. Stealth Mode (182°C) — Purple petal. Minimal visible vapour, maximum discretion.
Perfect for situations where you'd rather not announce your activities. 2. Efficiency Mode (188-199°C) — Green petals.
Gradual temperature ramping for longer, slower sessions. My default for evening use. 3.
Flavour Mode (193°C) — Yellow petals. Front-loads the terpenes beautifully for those first few spectacular hits. 4.
Boost Mode (210°C) — Orange petals. Dense, satisfying clouds without the harshness. 5.
Bong Mode (225°C) — Rainbow petals. Hidden mode designed for water pipe use. Maximum extraction, maximum heat.
Accessing Bong Mode: This one's hidden. Cycle through all four visible modes three times until the petals light up rainbow. Takes about 10-13 clicks total.
Worth knowing if you're planning water pipe sessions—it also disables the motion-sensor standby, so the device stays hot while you're passing it around.
Loading is straightforward. Medium grind, loose pack, gentle tamp. The Flow works best when not over-packed—too tight and extraction suffers. The side-loading design means you can load one-handed while walking, something that was impossible with previous PAX models.
One quirk: You can't blow the ABV out through the mouthpiece like you could with older models. The redesigned airpath means you need to scrape it out with the included multi-tool. Minor annoyance, but worth mentioning.
The 25-second heat-up is a genuine improvement. The Plus took 40-50 seconds. The Flow is closer to modern standards, ready before you've finished thinking about what you're doing.
Could your mum use this? Honestly, yes. The interface is Apple-simple.
The app is optional. The device does what you expect.

Cleaning & Maintenance 8.5/10
PAX finally made cleaning less annoying.
The Flow's redesigned side-loading oven is easier to access than previous generations. Pop off the magnetic door and you have full access to the chamber and vapour path—no more navigating narrow channels with pipe cleaners while cursing PAX's engineering team.
The Gunk Geography: Build-up mainly in the oven and around the oven door seal. The stainless steel vapour path stays cleaner than expected—the improved airflow means less residue accumulating in corners. The chamber itself needs regular attention, especially the edges where resin likes to accumulate.
Cleaning Timeline: - After 10 bowls: Light residue, still performing well - After 20 bowls: Flavour starting to muddy, quick brush-out helps - After 30+ bowls: Proper ISO soak for the mouthpiece and airpath
The Process: 1. Remove mouthpiece (lifts off) 2. Pop open oven door 3.
Brush out the oven (included brush works) 4. ISO soak the mouthpiece and oven screen 5. Wipe airpath with ISO-dampened cotton swab 6.
Dry completely, reassemble
Takes about 10 minutes for a proper clean. The included maintenance kit is actually useful—PAX has always been decent about including the right tools.
Daily maintenance: Empty while warm, brush the chamber, wipe the door seal. Thirty seconds after each session prevents major build-up.
For someone coming from the Plus, the cleaning improvement is noticeable. For someone coming from an S&B device with cooling unit maintenance, this is refreshingly simple. For someone coming from a DynaVap or glass-stem Arizer?
Still more faff than you're used to.

Portability 9.0/10
This is where PAX has always delivered, and the Flow continues the tradition.
The thing disappears.
Jeans pocket, jacket pocket, palm of your hand—wherever you put it, it vanishes. At 135g and a slim profile, it's lighter than the Veazy, more compact than the Crafty+, less conspicuous than anything Storz & Bickel makes. The flat sides sit flush against your leg.
There's no brick-bulge, no obvious outline.
I took the Flow to a gig. Slipped it in my front pocket, forgot it was there during the support act, used it in the queue for the bar during the interval, back in the pocket. Nobody noticed.
The matte black reads as "generic tech thing" to civilians—not obviously a vaporiser unless someone's specifically looking for one.
The LED indicators are subtle. No bright flashing lights, no obvious "I am currently vaping" signals. The haptic feedback means you can feel when it's ready without watching it.
Stealth Mode runs at 182°C with minimal visible vapour—genuinely discrete for public use.
In terms of pure discretion, PAX has this dialled in better than anyone else.
Could you use it at the cinema? Yes. A concert?
Yes. A suspicious family gathering? Probably.
The Flow is the ultimate stealth portable for people who need to be invisible.

Value for Money 6.5/10
And here's where the comeback analogy has its limits.
Because seeing Take That at Wembley wasn't cheap. The Flow costs £255—premium pricing for a device that's good but not reference-standard.
At this price point, you're in Mighty+ territory (£245), above the Veazy (£219), above the PAX Plus (£135), below the Venty (£295) and TinyMight 2 (£299). The question is: what are you paying for?
You're paying for: - Design. Genuine premium aesthetics. - Stealth.
Best-in-class discretion. - The polish PAX has always delivered. - USB-C charging (finally).
- The brand, honestly.
You're not paying for: - Reference-tier vapour quality. The Flow is 8/10, not 10/10. - Class-leading efficiency.
The Mighty+ at £10 less delivers noticeably better extraction. - Value. The Veazy at £36 less matches or exceeds the Flow's vapour quality.
If you're doing pure performance maths, the Flow loses. The Mighty+ extracts better. The Veazy costs less.
The TinyMight 2 offers superior on-demand hits and wider-open airflow.
But that's not why people buy PAX devices.
People buy PAX because they want something beautiful on their coffee table. Because they want to pull out a vaporiser that looks like premium tech rather than a medical pager. Because design matters to them more than the spec sheet.
For those people, the Flow is worth it. For everyone else, there are better values.

The Verdict
Six weeks in, the Flow has earned a place in my rotation.
Not the top spot. Not even top three. But a genuine, regular place—the vape I reach for when I'm heading out and stealth matters, when I want something that fits seamlessly into a night out without announcing itself, when I'd rather have something beautiful in my pocket than something optimal.
I publicly said PAX had lost the plot. I was wrong.
Not completely wrong—the Plus deserved the criticism, the price premium was always questionable, the "lifestyle brand" energy wore thin when the product didn't deliver. But the Flow? The Flow actually works.
The redesigned chamber breathes. The vapour satisfies. The 25-second heat-up stops you from reaching for something else.
Sarah watched me pack the Flow for the third weekend in a row.
"You're actually using that one," she said. "I thought you said PAX was finished."
"Comeback tour," I said.
"Like Take That?"
"Exactly like Take That."
She rolled her eyes. But she understood.
This is the Patience era. PAX came back older, wiser, and released something the critics had to respect. Not chart-topping dominance.
Not the cool flagship everyone wants. Just a mature, respectable device that does what it promises.
They aren't trying to be the Mighty+ anymore. They're just trying to be genuinely good at what they do.
And that? That's enough.
Who is this for? - Design-conscious users who want stealth that works - PAX 3/Plus owners ready for what the brand should have delivered years ago - People who prioritise aesthetics alongside performance - The "I want a vaporiser that doesn't embarrass me in public" crowd
Skip if: - You prioritise value—the Veazy delivers comparable vapour at £36 less - Raw performance matters more than discretion—the Mighty+ outperforms it at £10 less - You need all-day battery—the Air MAX's swappable cells are better suited - You're sworn off PAX and nothing will change your mind
