Every now and then, regardless of technology, a device comes along that raises the bar for all that follow. In the vaping world, those devices usually feature the letters “DNA” in the name, and three digits in the price. So, when a stylish, top-tier performance mod like the Modefined Sirius comes along at a VERY competitive price point, enthusiasts should take notice.

I’ve used vape mods that are refined. And I’ve used mods that qualify as rugged. Very rarely does a device have both descriptions covered. The smoothly machined, diecast zinc alloy frame is adorned with plates of anodized aluminum, and a nickel-plated 510 connection.

Speaking of this connection – the top of the Modefined Sirius could likely survive a few spins in an industrial rock tumbler. The 30mm-wide top plate is practically bolted down, and the 510 connection is equally as solid. Plus, it can accommodate all but the most obtuse atomizers and tanks without overhang, so that extra girth is worth every ounce.

The round fire button and metal operation keys are all extremely solid, and never rattled, no matter how hard I tried to find flaws. Though there is no “right” way to hold the Sirius mod, the ribbed section on the rear of the device seems more appropriate for positioning inside the crook of the palm. That said, the Sirius is equally comfortable in a thumb or trigger grip.

But the “rugged” side comes out a bit when noticing the lanyard/belt clip opposite the 510 connection. Though I think the Modefined Sirius is a bit too heavy to hang around my neck at work or vape conventions, I can see it sitting nicely on a tool belt or other piece of gear. This is a nice touch within a design that seems to speak to multiple audiences.

Speaking of design, I just need to say it – the Modefined Sirius is a very attractive vape device. Each of the available color schemes feel like they belong on high-end electronic devices, and not garish toys, like so many other mods available today. My test model is a subdued, but striking anodized cadet blue, with stainless and chrome accents to add some visual flourish.

About six months ago I made an impassioned plea for vape device manufacturers to start implementing action/enter buttons, rather than continuing to rely on the tired, “short/long press” of fire button scheme. Though I know it has nothing to do with me, I still feel like many companies listened, and the Modefined Sirius might be the best implementation of this yet.

Using the bright, full-color TFT screen, newcomers and veterans alike will easily navigate the Sirius menus, which basically require users to hit the action button, make the necessary adjustments to functionality, then close the process with another tap of the action button. Not only is it extremely linear and intuitive, but the process also helps stave off pocket fires and adjustments.

The screen itself isn’t quite as detailed as hi-res offerings like the SMOK ProColor, but Modefined gets the most from the 0.96-inch space, with clearly delineated menus and smart use of color contrast to keep things clear, even in direct sunlight.

After doing hundreds of these reviews, it can become tiresome to write about the quality of a vape mod fire key – honestly, how many ways are there to say, “Fire button gooooood” or “Fire button baaaaaaaad?” But, indeed, the fire button is a highlight of the Modefined Sirius. Mostly because it feels like a natural extension of the entire mod, rather than a tacked-on piece, made by the lowest bidder.

I’m also happy to report I experienced no misfires or odd performance quirks, using possibly the widest range of atomizers I’ve tried to date (including some seriously dodgy old tanks I dusted off for another review). The Modefined Sirius handled them with ease, with all tanks and RDAs sitting flush, firing quickly, and never getting excessively warm.

I feel like I’m gushing a bit, so allow me to balance the scales and acknowledge one thing I wish was better on the Sirius mod – battery life. Though not terrible by current dual-18650 device standards, once I took the Sirius above 100 watts for any length of time, the battery life dropped considerably, giving me roughly five hours of moderate use before low-power warnings populated my screen.

Of course, higher-wattage vaping will naturally use more battery power, but on a device with 100 additional watts of headroom, this was just a little surprising.

I read and watch a lot of vape reviews, and it always amuses me to hear “I haven’t stopped using it!” or “This is my new everyday mod!” while filming the video in front of a shelf filled with expensive vape devices. How could one person have SO MANY “go-to” devices?

Well, I’m about to become one of those reviewers. Because I’m currently on a business trip, and packed four vape devices for the week. Yet, I’ve only used one – the Modefined Sirius. And I only plan to use one for the rest of my stay. The combination of comfort, functionality, power and performance have made this my true “daily driver” whenever using a traditional tank/mod setup.

In power/wattage mode, the Modefined Sirius sings all the way to its advertised 200-watt limit, never once balking, even at the max output level. I’m assuming there are protection measures built in, but I never saw one during my testing, and the Sirius’s zinc alloy exterior didn’t get warm once, even when consistently hitting at top power.

Moving to temperature control, I was happy to see the Sirius performed equally well with whatever coils I threw its way. Using my usual Ni200 test rig, the Sirius quickly got up to temperature, allowing me to adjust wattage on the fly until I nailed down the perfect combination. Titanium coils offered similar results, though I felt like the ramp-up was a TOUCH slower – perhaps in part to their slightly lower resistance. It was nothing dramatic, nor did it affect vape quality, but it was noticeable during testing.

Stainless steel coils performed extremely well, both in power and TC modes, and became my preferred setup for TC vaping with the Sirius.

If there’s any slight knock against the Sirius’s TC performance, it’s that the preset configurations seemed a bit underpowered – something I’m noticing on newer mods I’ve reviewed. Despite initial frustrations when vaping this way, I imagine this is done intentionally, to prevent new users from overheating their coils. As a safety measure, I can’t say I disagree with the approach. Experienced TC vapers will have no problem adjusting to their liking, and TCR functionality will only enhance their enjoyment.

The Modefined Sirius also features a bypass mode, and it works as intended, even if it only furthers the battery drain. In my short time using this mode, I watched my battery levels drop noticeably.

The Sirius was also able to vape as a passthrough while charging via the USB port, but this is NOT advertised in the included documentation, and as such, I would strongly encourage users to not do this until Modefined indicates it is a safe practice.

That said, the onboard 2-amp charging works surprisingly well, bringing my 18650s to full charge in approximately 2.5 hours. I still always recommend external charging, but if you’re in a pinch, this is a good fallback option.

Based on what I just wrote, it’s pretty clear the Modefined Sirius is a fantastic vape device, offering top-tier performance at a VERY attractive price point. Does it offer the full customization of a DNA device? No. Is it the most high-tech mod available? Also no. But it offers true 200-watt power, easy operation, and stutter-free performance through and through, never once balking even when I tried to throw some curveballs its way.

As we’ve learned over the years, there are no “perfect” devices, and the Sirius has a few minor chips in its anodized armor, so it doesn’t get a “perfect” score. But as a complete package, the Modefined Sirius is easily one of the best combinations of form, function and quality I’ve seen to date, and I cannot recommend it enough.
