GeekVape FLINT AIO MTL Starter Kit Review

The mouth-to-lung (MTL) vaping resurgence is officially in full swing. It’s not a fad. It’s not a trend. It’s the industry coming full-circle, bringing vaping back from the land of “sport” and placing it in front of ex-smokers, where these products belong. And maybe that’s the reasoning behind the name of the all-new GeekVape Flint MTL starter kit.

The Flint kit is described as “the ultimate vape pen kit” with a laser focus on use with nic salt liquids and MTL vaping. The compact, 22mm diameter device is designed for simplicity, with a 950mAh integrated battery, and single-button operation to control three different voltage outputs.

A simple LED light system reflects power levels, device warnings and mode selection, while the companion tank shows off a new set of proprietary MTL-focused coils.

But this is no monotonous “stiff draw” vape – the tank includes an adjustable airflow ring, with five different options to cater to a wide range of vapers.

Simple and pocket-friendly is the name of the game with the GeekVape Flint kit. This compact device is barely 94mm tall WITH the tank attached, and has a pretty reserved color palette, meaning it’s an ideal device for stealthy, unobtrusive vaping.

The Flint’s finish and machining is top notch, which we’ve come to expect from GeekVape. What I liked most was how seamlessly matched these pieces are. While some “kits” are really just disparate parts being hobbled together to move product, the Flint kit is truly designed to go together – to the point that other appropriate tanks didn’t look QUITE right when attached. (Don’t get me wrong, they worked… but the Flint MTL tank is just a better fit for anyone who buys this device.)

The single-button operation is fairly straightforward, and becomes second-nature in a few minutes. For those more experienced with advanced vaping devices, the simplicity might be a little disconcerting. But the three-setting power output works as advertised, even if I found myself struggling to get a little more control than the preset voltage levels.

The Flint MTL tank is pretty standard for modern mouth-to-lung atomizers. That is, to say, stocked with a narrow ULTEM drip tip, small, low-juice flow coil system, and minimal juice capacity. In other words, don’t try and put your standard VG-heavy juices in here – they won’t work. This is a nic salt liquid machine, and sings the loudest when used as such.

Standout Features

While the kit is pretty straightforward, the Flint coil system is notable for its longevity. Each of the included MTL coil heads – 1.6 and 1.2 ohms, respectively – are no-nonsense affairs, made of food-grade organic cotton, and little else. Don’t go looking for complicated mesh arrays, or special hemp-based juice flow. They’re just coils, and they don’t mess around. Each of the test coils I received lasted well beyond two weeks when used with nic salt juices, with barely any loss in flavor and vapor production.

I should note, the box claims only the 1.6-ohm head is designed for nic salt juices, but don’t be fooled – each of these atomizers are to be used for MTL purposes only.  And when used this way, I managed nearly a month’s worth of collective vaping before having to buy new heads.

Vaping the GeekVape Flint Kit

What can I say? The Flint kit is a rock-solid MTL device, with few bells, whistles or distractions to interfere with the task at hand – satisfying vape quality. So, when I tested it, I tried to use it as its target buyer would – intermittently, without pushing it beyond reason or capabilities. Under those circumstances, the Flint did an admirable job.

Though I admit to impatiently chain vaping to start, the high-nic liquids I used quickly slowed my roll, and I settled on a more-reasonable “hourly” vape schedule. This was the perfect way to enjoy the intense, concentrated flavor offered by the NS coils – especially after vaping higher-VG juices throughout the rest of my day.

I found that both of the coil heads were adept at delivering immediate bursts of flavor and warm vapor, even on the lowest wattage output. On the highest setting, the vapor was a little dry and hot, with less flavor concentration, so consider that when vaping more steadily. But overall, I enjoyed the results with these durable coil heads.

Vapor production was about on par with most current MTL atomizers. That’s to say, thicker and more satisfying than things were “back in the day” but still wispy when compared to sub-ohm devices. Oh, the Flint can put out some serious clouds when using it with direct lung hits… but I don’t think I need to warn you about vaping that way with high-nic liquids.

(Actually, maybe I do… don’t direct lung vape high-nic liquids, kids… bad things occur.)

Battery life on the Flint was decent, considering the size of the device and the 950mAh capacity. I managed roughly 5-6 hours of casual vaping on one charge before the mod began to throw low-battery warnings. Hardly newsworthy, but not terrible, either. Thankfully, the onboard charging was both quick and efficient, with little residual heat when charging.

Spinfuel VAPE Recommendation and Score

Pod mods are extremely popular right now, but they’re not the most cost-effective way to vape, should you want to use it more frequently. That’s why there’s a solid market for mods like the GeekVape Flint kit. This simple, potent little pen mod does a good job delivering the flavor and intensity of nic salt juices in a more-advanced format. There’s more control over the experience than with pod mods, while remaining as portable and convenient.

Plus, with long-lasting coils and solid flavor, it’s easy to overlook the middling battery life and slightly limited tank capacity. Overall, the Flint might not be our favorite MTL vape out there, but it makes a very strong case for anyone seeking something more substantial than a throwaway pod device.
