GROO Slim 9000 Review: Slim Disposable Vape, Big Clouds?

The GROO Slim 9000 is a disposable vape featuring a slim design, 9000 puffs, a 1.0Ω mesh coil, and bold flavour. With a 1400mAh battery and 15ml capacity, it balances compact style with long-lasting performance.

Let’s be honest. Disposable vapes with “slim” in the name can be a bit hit or miss. Some look sleek but struggle to perform. Others promise big puffs but feel bulky in the hand. So when the GROO Slim 9000 landed in our stash, the first thought was: Can this thing really deliver both style and substance?

With up to 9000 puffs, a 1.0Ω mesh coil, and more than 10 flavours packed into a device just 70 grams in weight, the GROO Slim 9000 positions itself as a minimalist’s dream. But under that slim aluminium casing lies a high-capacity 1400mAh battery and 15ml of e-liquid, hinting at something far bolder than its design suggests.

So, does this vape actually live up to the name? Is it just another disposable, or a smart pick for flavour lovers and cloud chasers alike? We gave it a proper Aussie test – here’s what we found.

1. First impressions and design

Right out of the box, the GROO Slim 9000 catches your eye. The body is exceptionally thin for a 9000-puff disposable, making it easy to slip into a pocket or vape pouch without bulking you up. It’s not flashy or overly branded, just clean lines, a soft matte finish, and just enough grip to feel secure in the hand.

Construction-wise, it uses a combination of high-quality polycarbonate and aluminium, so it feels light but not flimsy. There’s no rattle, no cheap clicky plastic – just a solid, compact feel that fits easily in your palm.

And yes, it’s a non-rechargeable device, which might raise a few eyebrows. But with a 1400mAh battery inside, GROO vape is betting you’ll get the full use out of all 9000 puffs before it runs dry. More on that below.

In terms of aesthetics and build, this vape nails the balance between portability and presence. It’s not a statement piece, but it’s sharp enough to earn nods in the pub.

2. Flavour delivery: Bold from the first puff

The star of the GROO Slim 9000 is undoubtedly more than 10 flavours. Some disposables in this range go heavy on sweetness or artificial cooling, but this one stays nicely grounded. You get a burst of tangy berry on inhale, a bit of mellow jam-like smoothness on exhale, and just enough coolness to keep things crisp – without overpowering your throat.

This blend works especially well with the 1.0Ω mesh coil, which heats consistently and pulls the best out of the layered flavour profile. Compared to lower-resistance disposables, this one doesn’t rush the vapour. Instead, it rewards slower, more measured puffs with full, well-rounded flavour.

The balance is perfect for:

• Ex-smokers who want something bold but not candy-sweet
• Casual vapers chasing everyday flavour consistency
• Anyone who prefers a “real” berry taste rather than artificial punch

You’re not getting an icy throat freeze here, but something far more refined. Even heavy vapers will appreciate the smooth draw and clean finish.

3. Cloud performance and airflow feel

Now here’s where it gets interesting. Despite the name “Slim”, this vape actually pushes more vapour than expected. Thanks to that mesh coil and tight airflow optimisation, the GROO Slim 9000 produces satisfying, warm clouds that don’t feel forced or overdone.

The airflow is moderately restricted, giving it a proper mouth-to-lung (MTL) style inhale. It’s tight enough to mimic a cigarette, which makes it ideal for people quitting smokes, but not so tight that it feels blocked or awkward. No need to draw hard – just a natural, smooth puff gets the job done.

What really stands out is the consistency of the draw. Unlike some devices that feel “off” after a few hundred puffs, the GROO maintains airflow integrity throughout. You don’t feel like you’re pulling through a clogged straw halfway in.

This is particularly noticeable during longer sessions. The airflow doesn’t overheat, the flavour doesn’t fade, and the coil doesn’t flood – something many disposables still struggle with.

In short: The GROO Slim 9000 offers a rich, cigarette-like draw with surprisingly generous cloud output. A quiet overachiever.

4. Battery life: Long-lasting without recharging

Let’s get to the big question: Can a non-rechargeable 1400mAh battery really power through 9000 puffs?

In our testing, the GROO Slim 9000 held up impressively. Even with moderate to heavy daily use – think 300 to 500 puffs a day – it lasted a full 8 to 10 days without noticeable drop-off in flavour, vapour, or draw strength. That’s very respectable for a disposable in this size bracket.

There’s no battery indicator light, but the consistency of performance makes it easy to gauge when you’re nearing the end. Once the flavour starts thinning and the draw feels weaker, you’re likely down to the last 100-200 puffs.

For most users, the lack of recharging is actually a plus. No cables, no waiting, no worrying about forgetting your charger. When it’s done, you’re done. Dispose responsibly and grab the next one.

5. Comparing with other 9000-Puff disposables

The 9000-puff category has become the sweet spot for vapers who want longevity without moving into the bulkier 20K+ models. So how does the GROO Slim 9000 compare to its rivals?

The GROO Slim 9000 wins out for portability, simplicity, and battery longevity. It may lack the rechargeability of others, but it delivers a more mature, consistent experience – especially if you’re not into overly sweet or icy profiles.

6. Pros and cons

To keep it real, here’s a no-fuss breakdown of where the GROO Slim 9000 shines – and where it could improve.

Pros:

• Clean, slim design that fits anywhere
• Smooth and consistent MTL draw
• Great battery life without charging
• Balanced, natural berry flavour
• No leaking, no clogging, no surprises

Cons:

• Non-rechargeable (might turn off tech-savvy users)
• Limited to one flavour per device
• No airflow adjustment (though it’s well tuned by default)

Still, for vapers who value performance over gimmicks, these cons are minor trade-offs.

7. Who is it best for?

The GROO Slim 9000 is made for:

• Ex-smokers who want a reliable, tight draw without the fuss
• Busy vapers who prefer non-rechargeables for simplicity
• Flavour-first users who appreciate refined blends over icy hits
• Anyone on the go who wants something slim, discreet, and ready

If you’re after massive clouds, sweet-as-sugar profiles, or adjustable airflow systems, this isn’t your vape. But if you want something that quietly delivers for days, this one belongs in your rotation.

8. A quiet performer with surprising power

Sometimes less really is more. The GROO Slim 9000 skips the gimmicks and delivers where it matters: flavour, consistency, and ease of use. Its slim body hides a powerful setup, and while it may not shout for attention, it earns respect with every puff.

It’s a disposable made for grown-up vapers. No flashy lights. No over-the-top sweetness. Just a reliable draw, full flavour, and a satisfying experience from start to finish.
