Alright, I was wrong. I have to admit that I wrote my Fuchai GLO preview with a skeptical tone. Not just because it’s another dual-battery mod with an LED light feature. But also because my last Fuchai – the uber-popular 213 – was completely incapable of firmware updates or anything resembling accurate temperature control.

So, yeah – my expectations were tempered going into this one. But I’m eating my words, friends. Because the Sigelei Fuchai GLO is one of the most surprising mods I’ve reviewed for Spinfuel VAPE. (And yes, spoiler fans, I’m giving it a very good score.)

As I always say, it’s far from perfect. But the Sigelei Fuchai GLO is a fantastic, competitively priced, dual-18650 mod that deserves credit for a lot more than an LED light show. Let’s see why.

Though the specs indicate otherwise, there’s just something about the Fuchai GLO that feels large, even if it’s comparably sized to the Aliens, Predators, ProColors and other mods in this category. This is likely due to its very basic shape, with is effectively just a rounded corner brick.

But it’s a comfortable brick. The soft, almost velvety texture of the zinc alloy exterior feels great in the hand, and actually offers a fair amount of grip. In turn, the rounded edges ensure the size never digs into your palm or fingers.

The GLO is shockingly light, considering its formidable size and shape. Of course, a pair of 18650s gives it adequate heft, but this is a somewhat hollow-feeling device, which brings long-term durability into question. No, I’m not going to drop the mod on purpose … but I might knock it over a few times for good measure.

One area of concern was the slightly raised, press-fit 510 connection, which seems as though it could come loose with extensive use. I didn’t notice any problems during my two weeks of testing, but compared to other mods in this range, the GLO’s doesn’t seem quite as secure.

The 510 is also offset, despite the mod’s frame bowing out in the middle. A slight design change to center the 510 would have made it possible for atomizers wider than 25mm to fit without overhang. I realize the technology within the Fuchai GLO might have made the design necessary, but I feel like this is a complaint reviewers point out regularly, present company included.

Still, all of my tanks and RDAs were able to sit flush on the Fuchai GLO, with no gaps from any device – even those legacy RTAs I refuse to give up for nostalgic reasons. Plus, even at high wattages, the connection and tanks manage to stay relatively cool.

Finally, the “star” of the show is the tremendous, 1-inch wide LED section that wraps around the base of the Fuchai GLO. Using either a selection of six preselected color schemes, or using fully customizable RGB fields, users can craft their perfect color combination. I’ve seen RGB controls before, but these adjust in real time to make an exact match.

Thankfully, though the LED band is quite large, the color it emits is softly-lit, so things never become too gaudy or overwhelming. And, of course, those interested in more subtlety can simply turn it off.

The SLYDR M Sub-Ohm Tank is the compact rendition of the SLYDR L Tank, featuring a 23mm diameter chassis with just 2.8mL juice capacity. There is the Sliding Top-Fill System, light-up O-Ring design, and a versatile family of coils that deliver great flavor or fidelity and ample clouds of vapor. Included in each SLYDR Tank is a set is a 0.4ohm SM2 Single Cylinder Coil with a wattage range of 40 to 75W and a 0.2ohm SM6 Triple Cylinder Coil with a maximum wattage of 120W. Airflow enters the tank through two large bottom airslots, integrated with a ball-bearing airflow design for a precision adjustment.

While I might like, or prefer, a larger juice capacity, I have to admit that the SLYDR M Sub-Ohm is definite a high-performance tank. The vape experience is akin to vaping with a SMOK BABY BEAST, though the coils are somewhat smaller, every bit of flavor and clouds are nearly par with the SMOK TFV8 tanks.

Beneath the bright lights, bells and whistles lies a 230-watt workhorse. And I’ll cut to the chase – the Fuchai GLO is capable of a LEGITIMATE 230 watts. Unlike so many similar mods which promise enough power to illuminate Cleveland, only to under-deliver, the GLO is smooth and steady all the way up the ladder – AND the mod stays cool to the touch throughout.

I won’t belabor this with tales of scorching my throat or uncomfortably warm vapes, let’s just say if you have any concerns about a device delivering on expectations, the Sigelei Fuchai GLO should put those thoughts to rest.

Mechanically, the Fuchai GLO is solid, even with the slightly hollow feel. The side-mounted fire button is made of the same zinc alloy as the frame, and has a nice feel, despite a little more rattle and play than I expected. In contrast, the front-mounted up/down adjustment buttons are firm and clicky, and function extremely well with minimal pressure needed to engage them.

The magnetized battery door stays nice and snug, and never once released unexpectedly. However, I noticed that the mod wasn’t quite level with the cells installed, and was somewhat wobbly on my desk. Though I never had it fall, it also never seemed perfectly stable, even with the ample width of the device.

The onboard menu system uses a standard 3-click operation, and allows for easy navigation of the straightforward option listings. Aside from an explanation of how RGB color wheels work, the options are clearly displayed on the vibrant, full-color, 0.96-inch OLED screen.

There, users will be able to quickly switch between wattage, stainless steel, nickel and titanium options, as well as five custom TCR slots. Additionally, they’ll be able to make minor adjustments to preheating, puff power and time settings with ease. The small screen has a nice resolution, allowing more information to be displayed without confusion.

And yes, there WILL be firmware upgrade capability with the Fuchai GLO, putting to rest a lingering concern from the 213 debacle.

Typically, I begin my testing with straight wattage vaping, but given the brand’s troubled history with accurate temperature control, I decided to start there.

Using my soon-to-be-famous stainless steel test coils, in my ever reliable GeekVape Ammit RTA, the Fuchai GLO effortlessly heated the coils to a precise temperature, with no warnings or coil protection mechanisms slowing me down. The resulting vape was as smooth as butter, and just as flavorful.

The Fuchai GLO has a max temperature of 570 degrees Fahrenheit, which seems a little low compared to similar devices, but given the rich, flavorful vape I enjoyed at just 475 degrees, I hardly think those remaining 30 are going to impact flavor chasers in any way.

Moving to wattage mode, I found the Fuchai GLO to work best at moderate levels. Though it was perhaps a touch of user error, due to inexperience, the GLO seemed a little inappropriate for higher-resistance coils, such as my ancient Kayfun Mini v3. At just 20 watts, it almost felt as if the Fuchai GLO wanted to fly higher than I’d let it.

Yet, when moving to a sub-ohm coil and raising the power to 65 watts, suddenly, it was like the device “woke up,” and rewarded me with huge, room-filling clouds and more deeper flavor. Perhaps this is just the nature of today’s high-power mods, but if a mod can handle 230 watts with relative ease, then 10% of that total should be a breeze, yet the Fuchai GLO seemed a little “off” at these miniscule levels.

Ending on a positive note, the Sigelei Fuchai GLO is my new battery life champion. With the LED bar activated, endless menu and RGB tinkering, and ample amounts of heavy vaping, the GLO gave me nearly 10(!) hours of active use. In non-testing conditions, I can imagine the mod going 12 or more – outstanding performance, considering how much is going on within the GLO’s circuitry.

As a reviewer, it’s my job to split hairs. So, in that sense, no, the Sigelei Fuchai GLO isn’t perfect. It has odd low-power performance. Its battery door is strangely bowed. And the chassis doesn’t seem as durable as the mod’s size would imply. There – hairs split.

As a vaper, I love the Sigelei Fuchai GLO. It’s a top-flight power performer at an unreal price point, simplified temp control, comfortable form factor, and a goofy but cool LED light bar. It might not be the deepest, most-customizable experience available, but the bottom line is that the GLO vapes like an absolute champion, and should be on your short list if you’re in the market for this type of device.
