Performance
Lost Mary Viz lists 55000 puffs against 50000 puffs for NEXA Ultra 50K Disposable, but this category is scored a tie. Both figures put the devices in the same high-capacity tier, and a 5000-puff gap on its own isn’t enough to call one device the stronger performer, especially with coil design (dual mesh coils on both) being identical on paper.
Battery
Battery capacity is close, at 850 mAh for Lost Mary Viz versus 900 mAh for NEXA Ultra 50K Disposable, and both are rechargeable via USB-C. The 50 mAh difference is small enough that it doesn’t translate into a clear real-world advantage, so this category is a tie.
Convenience
NEXA Ultra 50K Disposable wins convenience because it adds two features Lost Mary Viz doesn’t have: adjustable airflow and a display. Adjustable airflow lets a user tune draw resistance to preference, and an onboard display typically gives feedback like battery or e-liquid status. Lost Mary Viz has neither, which is the deciding factor here.
Value
There isn’t enough evidence to call a value winner. Pricing isn’t listed for either device, and while Lost Mary Viz specifies 15 flavor options against NEXA Ultra 50K Disposable’s unstated count, without cost figures or a fuller flavor lineup for NEXA, no fair value comparison can be made.
Lost Mary Viz suits buyers who want a straightforward disposable with a documented 15-flavor lineup and don't need airflow control or an onboard display.
NEXA Ultra 50K Disposable suits buyers who want more control and feedback, thanks to its adjustable airflow and built-in display.
The verdict
Neither device comes out ahead across the board. Puff count and battery capacity are effectively tied, so those specs shouldn’t drive a purchase decision either way. NEXA Ultra 50K Disposable pulls ahead on convenience thanks to adjustable airflow and a display, features that matter to users who want more control and feedback during use. Value remains an open question due to missing pricing data. The right choice depends on whether those convenience features matter more to you than a documented flavor lineup.
