Comparison · Four 40K-class disposables
Adjust MyRusher 40K vs Geek Bar, Lost Mary & RAZ
If you're shopping for a higher-puff disposable, MyRusher isn't the only option in the market. Geek Bar Pulse, Lost Mary MO20000, and RAZ TN9000 cover overlapping price ranges. Here's how MyRusher stacks up on the dimensions that matter.
Per-puff cost — the only objective metric
Most disposable reviews skip the math. Let's not. Per-puff cost is the cleanest way to compare devices because it's the one thing that doesn't depend on flavor preference or draw subjectivity.
- Adjust MyRusher 40K — 40,000 puffs at $22.99 = $0.00057 / puff
- Geek Bar Pulse 25K — 25,000 puffs at $19.99 retail = $0.00080 / puff (40% more per puff than MyRusher)
- Lost Mary MO20000 Pro — 20,000 puffs at $17.99 retail = $0.00090 / puff (58% more per puff than MyRusher)
- RAZ TN9000 — 9,000 puffs at $14.99 retail = $0.00167 / puff (2.9× more per puff than MyRusher)
MyRusher wins this metric — by a meaningful margin. If you're optimizing for nicotine cost per session and don't care about anything else, MyRusher is the rational choice. The 40K format is currently the cheapest legitimate way to vape per puff. Pair that value with the full lineup of adjust flavors and it's clear why Adjust Vape reorders keep climbing.
Draw profile — where they actually differ
Per-puff cost is one dimension. How the device feels is another, and here they differ more than the spec sheets suggest.
- Adjust MyRusher: Tight MTL, harder throat hit. Built for vapers who want a firmer draw than mainstream disposables. Closer to refillable pod systems than to other disposables.
- Geek Bar Pulse 25K: Adjustable airflow ring, ranging from medium-tight to loose. More versatile than MyRusher but never quite as committed-firm as MyRusher's tightest setting.
- Lost Mary MO20000: Medium MTL, loose-side. Friendly draw for first-time vapers, less satisfying for ex-sub-ohm users.
- RAZ TN9000: Medium MTL, the most "default" of the four. Comfortable but not memorable.
If draw firmness is your priority, MyRusher wins. If you want adjustable airflow, Geek Bar Pulse is the only one with a ring on the device. If you want a forgiving draw, Lost Mary or RAZ are easier first picks.
Flavor library
MyRusher ships 10 flavors. Geek Bar Pulse 25K has 25+. Lost Mary MO20000 ranges 18-22 depending on regional availability. RAZ TN9000 has around 15.
On raw count, MyRusher has the smallest library. On per-flavor quality, MyRusher's Sensory Lab calibration process means most flavors hit their target reference accurately — at the cost of a smaller catalog. Geek Bar's larger library has more variance: some flavors are excellent, some are mediocre. Lost Mary leans candy-sweet across most of its flavors. RAZ leans dessert-forward.
Honest assessment: if you want maximum flavor optionality, Geek Bar Pulse wins. If you want a curated, smaller library where every flavor was tasted-and-approved against a target, MyRusher wins. For typical vapers who settle into 2-3 favorite flavors and rotate, the library size doesn't matter much.
Build quality
All four devices are plastic-chassis with integrated mouthpieces. Build feel is roughly equivalent across the lineup; none of them feel cheap, none of them feel premium. USB-C is standard on all four (older 5K/9K disposables sometimes still ship micro-USB; that's not the case in this comparison group).
MyRusher's chassis is shared with MyCool — the lineup is consistent. Geek Bar Pulse 25K has a slightly more angular industrial design. Lost Mary devices tend to have softer rounded shapes. RAZ TN9000 is the most pocket-friendly form factor. Subjective; none of these are deal-breakers.
Availability and authenticity
Geek Bar, Lost Mary, and RAZ are mass-market brands with wide retail and online distribution. You can buy them at smoke shops, gas stations, and dozens of online resellers. The trade-off: counterfeits exist for all three brands, and price varies wildly across resellers (Lost Mary MO20000 lists from $14 to $30+ depending on the channel).
Adjust is direct-to-consumer only. You buy MyRusher from this site, full stop. The trade-off: you can't grab one at the convenience store. The benefit: every device you order comes from one warehouse with QR-verified authenticity. You're trading "availability" for "guaranteed real and consistently priced."
Verdict
For most vapers in 2026, MyRusher 40K is the best per-dollar pick in this comparison set — assuming the firmer draw profile fits your preference and you don't mind ordering direct. The puff-cost advantage is meaningful (40-190% cheaper per puff than the alternatives), and the Sensory Lab flavor calibration is a real differentiator.
MyRusher isn't the right pick if you want the largest possible flavor library (Geek Bar Pulse), if you want a more forgiving draw (Lost Mary MO20000), or if you specifically want a pocket-sized form factor (RAZ TN9000). Those are real reasons to buy elsewhere — but on the core "value per nicotine delivery" question, MyRusher leads this segment.
