At a Glance: Two of the biggest names in vaping have launched competing clear-tank disposable vapes. The Geek Bar CLR 50K and Lost Mary VIZ 55K are very similar on paper but look quite different in execution. These are two outstanding clear-tank disposables, but which one is better?
Geek Bar CLR 50K vs. Lost Mary VIZ 55K: Clear Tank Vape Comparison
The Geek Bar CLR 50K and Lost Mary VIZ 55K are two of the most formidable competitors in the new generation of clear-tank disposable vapes. They distinguish themselves from the Foger Switch Pro (and its myriad imitators) and the formidable Off Stamp X-Cube Crystal Cube, powered by Lost Mary, because they do not rely on reusable battery charging docks.
These are just pure, one-time-use disposable vapes. With no buttons or flavor control modes, they both focus on the most important performance elements that adult vapor consumers seek. They have a lot more in common than their rather different appearances would suggest at first glance. Both have fast charging, high puff counts, large e-liquid capacities, efficient atomizers, long-lasting battery power, and dual modes.
Geek Bar CLR 50K vs. Lost Mary VIZ 55K
On paper, these devices are remarkably close. The Geek Bar has slightly more e-liquid and a larger battery, while the Lost Mary advertises a higher puff count in both modes.
Rather than simply adding larger batteries and more e-liquid, Geek Bar vapes and Lost Mary have focused on efficiency, consistent flavor, and improved hardware.
Clear Tank Design: Geek Bar vs. Lost Mary
What makes the Lost Mary VIZ 55K and Geek Bar CLR 50K stand out from their popular stablemates is the use of a transparent e-liquid reservoir. Geek Bar still sells the Pulse 2 and Pulse X2 series with plenty of advanced features. The sturdy and impressive Lost Mary MT35K is also still quite popular. But all of these devices rely on a smart display that shows an estimate of remaining e-liquid. The VIZ 55K and CLR 50K provide a precise bird's-eye view.
Making this setup work requires much more than just adding a transparent plastic panel. It involves a total reworking of the device hardware and how e-liquid is stored.
Traditional disposable vapes rely on nicotine salt e-liquid absorbed into cotton polyfill, making it impossible to directly inspect the remaining liquid. Rip off the top of any traditional disposable vape and you will find this saturated material. It helps to reduce leaking, and the materials are always wicked, i.e., you don't need to wait for them to become soaked before vaping or else risk taking a dry hit. Of course, as the quantity of e-liquid is reduced, the correspondingly older coil combined with fast-depleting polyfill can result in some harsh hits. This was a big weakness in the old BC5000 disposable vapes, which is why brands like Fifty Bar made a point of utilizing anti-burn technology.

Geek Bar CLR 50K vs. Geek Bar Pulse X2 50K
Compare the Geek Bar CLR 50K and Geek Bar Pulse X2 50K. Both deliver up to 50,000 puffs, dual-mesh coil technology, and upgraded Vapor Processing Units (VPU). The CLR features a transparent e-liquid tank, while the Pulse X2 offers a larger battery, slightly greater e-liquid capacity, and a curved display. The differences in dimensions, mostly found in the width department, are attributable to the screen that wraps around the front of the Geek Bar Pulse X2.
The Geek Bar CLR 50K looks like a Geek Bar Pulse X2 that traded the 3D curved screen for a clear panel to view the e-liquid level. There is nothing wrong with this, as the Pulse X2 is also their longest-lasting and most capable disposable vape. The Geek Bar CLR 50K essentially matches it stride for stride.
The Geek Bar CLR 50K retains the familiar user interface of the Geek Bar Pulse family as well. There are no buttons. A simple switch turns the device off and switches between modes. It also tweaks the airflow, which cannot be changed independently. This approach puts fewer holes in the shell and allows for tighter tolerances and less chance of leaking or passively emitting cloying odors from your pocket or desk drawer.
By removing the ability of the customer to change airflow parameters, some level of customization is removed. But this also allowed Geek Bar engineers to more precisely calibrate the wattage output and work toward keeping the puff count high and the chance of dry hits or prematurely wearing out the atomizer low. An upgraded version of Geek Bar's proprietary VPU, or Vape Processing Unit, is the brains in all three of the modern disposables.
According to Geek Bar, their VPU platform manages heating, fluid transmission, and vapor production. The manufacturer claims its technology improves vapor volume by 23.7%. While the Pulse X2 does have a slightly larger battery than the Geek Bar CLR 50K, it also has a rather fancy screen and e-liquid monitoring system to operate. The simpler CLR 50K seemed to have equivalent or better life between charges despite having a 900mAh battery versus the 1000mAh battery found in the Geek Bar Pulse X2.
The 3D Waterfall Glow display adds visual flair, but the transparent tank remains the defining feature. The CLR is a self-contained rechargeable disposable, not a modular device with a reusable battery dock.
Lost Mary VIZ 55K versus Lost Mary MT35K
The Lost Mary VIZ 55K makes a clean break from the Lost Mary MT35K, which was in fact a more efficient and scaled-up Lost Mary MT15000. The center-mounted mouthpiece, high-quality clear plastic shell, and revamped airflow control make it a totally new generation of device.
Visually, the unconventional approach of the Lost Mary VIZ 55K is immediately obvious. Its transparent reservoir surrounds a central hardware stack illuminated by a 360° Visible LED Display. The result is a sleek, almost futuristic device that is visually distinctive without relying on cartoonish graphics. The CLR 50K is also mercifully free of the traditional galactic graphics and flashing planets of its stablemates. The VIZ certainly has more going on graphically than the CLR 50K.
Lost Mary VIZ 55K: Triple Coil Technology
Inside is Lost Mary's advanced triple coil technology, engineered to deliver consistent flavor and extract more puffs from a relatively modest 16.7mL reservoir. The VIZ is surprisingly compact considering its advertised 55,000-puff capacity.
Its combination of illuminated tank, efficient coil design, and balanced airflow makes the VIZ a particularly formidable competitor.
Regular Mode vs. Pulse and Boost Mode
Both devices offer two operating modes. Regular Mode prioritizes longevity with lower output, while Pulse or Boost Mode increases power and vapor production. What is interesting is that both devices boast rather robust puff counts despite having less than 20mL capacity. This was accomplished through improved atomizer designs.
With 50mg nicotine strengths on tap, pure wattage and RDL airflow do not provide optimal flavor. Instead, both devices balance efficiency with performance. Both seem to pack a fairly similar punch, and neither seems to have spitting issues. At the end of the day, they are similar enough that flavor preference and availability are going to decide the day.
Geek Bar CLR 50K vs. Lost Mary VIZ 55K Flavors
Hardware is only half the equation. Geek Bar and Lost Mary are both established names in disposable vape flavors, but their lineups have distinct personalities. Geek Bar flavors are generally more heavy-handed and boisterous. Lost Mary flavors are a bit more refined, although still quite punchy compared to bottled nicotine salts.
The Geek Bar CLR 50K offers 25 flavors, including familiar mint and fruit combinations alongside unusual options such as Coffee and Blueberry Jam. The Lost Mary VIZ 55K offers 20 flavors, emphasizing the brand's popular tropical, sour, and mixed-fruit profiles.
Geek Bar CLR 50K: All 25 Flavors
Lost Mary VIZ 55K: All 20 Flavors
Which Has Better Flavors?
There is no shortage of excellent flavors in either collection. Geek Bar offers a slightly larger selection and more unusual options. The Lost Mary VIZ leans into the tropical fruit combinations and sour profiles that helped establish the brand. If Geek Bar is well known for its adoption of sour and sweet confection-style vapes, Lost Mary has certainly closed that gap with a vengeance.
In our experience, the Lost Mary VIZ has a slight edge in flavor delivery and overall draw characteristics. Its advanced coil design produces excellent flavor, while the airflow feels particularly well matched to the hardware. But this is a subjective distinction, not a runaway victory.
Geek Bar CLR 50K vs. Lost Mary VIZ 55K: Our Verdict
These are two exceptionally well-matched disposable vapes. Both offer clear tanks, massive advertised puff counts, rechargeable batteries, and sophisticated atomizer technology.
The Geek Bar CLR 50K has the advantage of a larger 900mAh battery, slightly more e-liquid, and Geek Bar's established VPU platform. It is also the more familiar choice for adult vapor consumers who already enjoy Geek Bar Pulse devices. It really does appear to just be a Geek Bar Pulse X2 with a clear panel on one end.
The Lost Mary VIZ 55K has the more distinctive design, a higher advertised puff count, and a particularly impressive triple coil system. Its 360-degree illuminated tank is functional without being unnecessarily flashy. It is slightly taller but is a much slimmer and more easily handled device.
Our preference is the Lost Mary VIZ 55K for its flavors, appearance, and airflow. But the margins are razor-close. Both represent a substantial advance over the opaque polyfill disposables that dominated the market only a few years ago.
