Please allow me to start this review with a retraction. In my preview of the Wismec Reuleaux RX2 20700 mod, I incorrectly stated this device would have a 300-watt capability, and speculated upon this figure. Upon receiving the mod, I quickly realized this is a 200-watt device, but forgot to update the preview accordingly. We apologize for this oversight – the preview has since been corrected.

That said, I’m also somewhat relieved that I was misinformed about the RX2 20700’s capabilities. While I was prepared to be disappointed by a dual-battery mod trying to hit 300 watts, I was excited to see how well this compact cloud machine could handle 200 – and I was rewarded by a high-performing mod that continues Wismec’s recent run of success.

Wismec Reuleaux RX2 20700 Kit Review – Spinfuel VAPE

Normally, my first reaction to a vape mod is related to size. Or bold design. Or some standout feature. Here, my first reaction was, quite simply, “Damn, that’s really green.”

Indeed, Wismec went a little left of center with one of the RX2 20700 color options, but looks are subjective. Performance isn’t. And this kit is set up to perform, right down to the included Gnome sub-ohm tank.


The RX2 20700 is immediately identifiable as a Wismec mod. With its now-iconic hexagonal shape, large OLED display and stout design, the company has stayed on brand with this device. Speaking of which, the expected JayBo logo branding returns here, on the sizable aluminum fire key.

On its own, the RX2 20700 is surprisingly trim and compact. When you realize this device is actually designed for a pair of taller, thicker 20700 cells, it goes from “surprising” to “amazing.” I don’t know how these manufacturers push so much technology into such small spaces, but they did a phenomenal job crafting this mod.

In a nice touch, Wismec included a pair of 18650 battery adapters, because those larger cells aren’t included. (Which, as we’ll discuss in a bit, doesn’t matter much on the RX2 20700. The rear sliding battery door is an interesting “push/pull” mechanism that seems flimsy at first, but holds everything in place nicely, whether in 18650 or 20700 mode.

Finally, the centered stainless steel 510 is another positive, as it is near bomb-proof. I’ve had issues with loose connections on older Reuleaux mods, but don’t foresee this happening on the RX2 20700.

Operating the Wismec Reuleaux RX2 20700 mod

Wismec has a system in place, and it looks like they’re going to use it until they devise something even better. But that might be hard to do, considering how streamlined the operations are.

The sharp 1.3-inch display uses the company’s now-standard “hexagon” display boxes, which clearly show wattage/temperature, battery voltage, dual battery meters, coil resistance, and current mode – all without ever crowding the screen or becoming illegible.

If only the button presses were as responsive as in previous editions of this system. It’s not a software/firmware problem, though. Instead, the RX2 20700 suffers from an oddly flimsy and mushy up/down control input, which is recessed too far into the body to ever provide a confident press. Plus, with both directional located on a single button, it’s far too easy to make incorrect inputs.

Though I got used to the quirks, the control button was a rare misstep on this otherwise impressive mod. It’s even more surprising when considering how strong and clicky the oversized fire button is on the RX2 20700.

The menus themselves are standard fare. Three clicks get you into the straightforward menu trees, where you can easily select modes, coil types, display direction, stealth mode and more.

(I find it funny that they’d include a stealth mode on a bright lime green device, but I digress…)

Finally, the RX2 20700 has true 2-amp onboard charging, which managed to get a near empty pair of 20700s back up to speed in record time. The mod stayed relatively cool while charging, but I still recommend external chargers whenever possible.

Revisiting the Gnome Sub-Ohm Tank…

This is my second go-round with the included Gnome sub-ohm tank, and I was happy that nothing has changed since my first time vaping one. Though the tank guzzles juice with the best of them, the tradeoff is a fantastic balance of rich flavor and ample vapor.

Just like before, the pre-installed WM02 dual-coil head produced some of the most enjoyable vapor I’ve had in some time, even at low wattages. The squat layout of the 4mL tank keeps the coils close to the mouthpiece, which results in warmer, more nuanced clouds than many of today’s taller tanks can provide.

The WM03 triple coil head is also a strong performer, but I found the WM02 to be the better of the two, with more longevity, and richer flavor in each puff. The WM03, by comparison, seems a little more designed toward cloud production, muting the flavor a bit. Both coils are winners, but I know which one I’ll be replacing when the time comes.

The Gnome also has an optional RBA deck to purchase, but it was not included in the kit.

Vaping the Wismec Reuleaux RX2 20700 mod

As a vaper, there’s something comfortable about familiarity. And the Wismec Reuleaux RX2 20700 is as comfortable as a pair of slippers. Though it’s modified throughout, the shape, design, operations and overall feel are just as we’ve come to love on Wismec’s previous outings. It’s not quite as palm-friendly as the RX Gen 3, nor as slender as the RX 2/3 (in dual-battery mode), but the RX2 20700 still feels great in the hands.

And you’ll want a comfortable grip when getting a hold of this power. As expected, the RX2 20700 goes to 200 watts without even hiccupping. Using a trusty Anarchist Riot RDA and an ultra-low Kanthal build, the RX2 20700 ramped up in no time, producing an almost instant blast of flavorful vapor. And that was on the “normal” preheat setting. I tested the other preheat settings, but frankly, I doubt most vapers will be more than satisfied by the default ramp-up power.

In temperature control mode, I fought with the quirky up/down control button, but otherwise had no issues setting desired temperature, adjusting wattages on the fly, and ultimately dialing in my ideal TC settings in TCR mode. Unlike many recent mods, the RX2 20700 easily handled every coil I threw at it, with no jumpy ohm readings, or random coil warnings to endure.

Unfortunately, the battery life is just average. In the default 20700 setup, I enjoyed 4-5 hours of steady vaping between 65-80 watts, before power began to wane. In the 18650 configuration, I actually enjoyed around a half hour more vape time, but this was accomplished without tinkering with menus or swapping tanks repeatedly, so the difference is negligible.

At higher (110+) wattages, the RX2 20700 began to lose life faster than a carnival goldfish. Though the device continued to provide smooth power and enjoyable vape quality, watching the battery meters drain so quickly was frustrating.

Needless to say, I still don’t see 20700 cells as the future of advanced vaping technology.

Wrapping up … and Score…

Despite two notable setbacks – the mushy control button and underwhelming battery life – the Wismec Reuleaux RX2 20700 is a strong, high-performing mod that I continue to enjoy. I may have struggled with the up/down control button, but it always got me where I needed to be.

The Gnome tank makes a stylish, flavorful counterpart that is well worth the extra $15 for the kit.

Some will gripe that Wismec has gone to the well a few too many times with this design aesthetic, but I say “no way.” It may not be perfect, but the RX2 20700 was reliable, enjoyable and flavorful – three of my main criteria for a quality vape mod. If you’ve held off from buying any of Wismec’s previous Reuleaux devices, this is a strong case for taking the leap.
