Tasting Notes — Inhale to Exhale
First Inhale
The first thing that hits you is a dark, slightly tart blueberry — not the candy-store kind, but something closer to a handful of wild berries picked off the bush. There’s an immediate depth here, a tangy bite at the edges that tells you Lost Mary put real thought into the flavor formulation. The sweetness holds back at first, letting that tartness lead.
Mid-Draw Body
By mid-draw, the sweetness curve rises and fills out the profile. The berry becomes richer, rounder — think the difference between a blueberry skin and the soft flesh inside. A faint jammy undertone surfaces, and the ultrasonic atomization keeps the vapor remarkably smooth, almost silky on the palate. No harshness, no chemical edge.
Exhale
The ice shows up on the exhale, and it’s measured — a cool breeze rather than a full arctic push. It lifts the blueberry without burying it, which is exactly what a good ice pairing should do. The cooling hits the back of the throat gently, then fades clean. You taste berry all the way through the exhale.
Aftertaste
A pleasant berry trail lingers for several seconds after each puff. It’s not cloying or syrupy — more like the faint memory of fresh blueberries on your tongue. Makes you want to take another draw. This is where the Ultrasonic 35K separates itself from cheaper blueberry ice options that leave nothing behind.
Dimension-by-Dimension Scoring
Sweetness — 70/100 (Prominent)
The sweetness is a driver here, but it never crosses into cloying territory. Lost Mary strikes a balance where the sugar supports the berry rather than overwhelming it. Compared to RAZ’s DC25000 Blueberry Ice at 74, this reads slightly more restrained — a conscious choice that pays off in complexity.
Cooling — 66/100 (Icy)
Gentle, deliberate cooling that frames the berry profile without freezing it out. The ice onset is gradual, arriving on the exhale and dissipating cleanly. If you’ve ever bitten into a chilled blueberry straight from the fridge, that’s the temperature we’re talking about — pleasant, not punishing.
Authenticity — 78/100 (Faithful)
This is where the Ultrasonic 35K earns its highest mark. The blueberry reads as real fruit, not candy. There’s tartness in the skin, sweetness in the flesh, and a wild-berry depth that most disposables simply miss. The ultrasonic atomization seems to pull out subtleties that traditional mesh coils flatten. Faithful to the actual fruit.
Aftertaste — 74/100 (Rich)
A lingering berry trail with genuine complexity — the tartness returns faintly on the aftertaste, creating a layered finish rather than a one-note fade. Our panel noted this stays interesting for 4-5 seconds post-exhale, which is above average for a disposable at this price point.
Throat Hit — 48/100 (Smooth)
Remarkably smooth for a 5% nicotine device. The ultrasonic delivery system softens the throat sensation considerably — you get satisfaction without the scratch. Users who prefer a stronger kick might find this too gentle, but for all-day use, the low throat hit is actually a strength.
Aroma Intensity — 75/100 (Full-Bodied)
Pull the device from your pocket and you’ll catch a sweet berry fragrance before you even take a draw. The aroma matches the actual taste profile well — no disconnect between what you smell and what you taste, which speaks to formulation quality. Full-bodied without being room-filling.

How It Compares
Among blueberry ice disposables on our blueberry pillar page, the Lost Mary Ultrasonic 35K sits at the higher end with a 71 overall. Here’s where it lands against the field:
| Device | Overall | Auth | Cool | Edge |
| Geek Bar Pulse X 25K | 73 | 80 | 69 | Best authenticity |
| Lost Mary Ultrasonic 35K ★ | 71 | 78 | 66 | Smoothest draw |
| RAZ DC25000 | 70 | 73 | 71 | Best ice kick |
| RELX Nova 30K | 70 | 76 | 55 | Most subtle |
| Lost Mary MT35000 | 70 | 75 | 68 | Fuller body |
The Ultrasonic 35K claims second place, just behind the Geek Bar Pulse X 25K which edges it on authenticity (80 vs 78). Where the Lost Mary wins is smoothness — a throat hit of just 48 makes it the gentlest blueberry ice on the chart, ideal for vapers who want flavor without friction.
Best Paired With
- Morning coffee — The tart blueberry opening cuts through dark roast beautifully. Set the flavor dial toward tart for the best pairing.
- Afternoon break — Between meals, the gentle cooling and moderate sweetness hit a comfortable middle ground without overwhelming your palate.
- After dinner — Turn the dial to smooth. The dessert-adjacent berry sweetness works as a satisfying palate cleanser after a heavy meal.
- Late-night sessions — Low throat hit and calm cooling make this an easy draw when you’re winding down. No harshness to jolt you awake.
The Bottom Line
Lost Mary’s Ultrasonic 35K delivers one of the most refined blueberry ice profiles we’ve tested this year. The ultrasonic atomization genuinely earns its name — the vapor is smoother than any mesh coil alternative at this puff count, and the flavor complexity, particularly that dark wild-berry tartness, puts it a cut above average. At 71 overall, it’s not the absolute king of blueberry ice (that crown still belongs to the Geek Bar Pulse X), but it’s the device we’d recommend if smooth, all-day comfort matters more to you than raw intensity.
Our verdict: Recommended — especially for vapers who prize smoothness and authentic berry flavor over aggressive cooling or throat hit.

Common Questions
What does the Lost Mary Ultrasonic 35K Blueberry Ice taste like?
A dark, slightly tart blueberry with wild-berry depth and gentle ice on the exhale. Less candy-like than most blueberry vapes — closer to real fruit. The cooling is moderate, more cool breeze than arctic blast, and the aftertaste leaves a pleasant berry trail.
How does the flavor dial work on the Ultrasonic 35K?
The spin-to-enhance dial on the device adjusts the flavor profile between smooth and tart. Turning it one direction emphasizes the sweet, dessert-like side of the blueberry; the other direction brings out more tartness and bite. We tested Blueberry Ice across both settings — the tart setting brought out more of the wild-berry character we preferred.
How long does the Lost Mary Ultrasonic 35K last?
In Normal Mode, Lost Mary rates it at 35,000 puffs. In Boost Mode (higher vapor output), expect closer to 20,000. The 800mAh rechargeable battery and 20mL e-liquid capacity mean you’ll need to charge via USB-C periodically, but the juice should last most users 2-3 weeks of regular use.
Is the Ultrasonic 35K Blueberry Ice too sweet?
No. At 70/100 on our sweetness scale, it falls in the “Prominent” range — noticeable but controlled. The tartness in the blueberry profile and the cooling on the exhale both work to balance the sugar. If you typically avoid candy-sweet vapes, this should sit comfortably within your range.
What’s better — Lost Mary Ultrasonic 35K or Geek Bar Pulse X for Blueberry Ice?
The Geek Bar Pulse X 25K scored 73 vs the Ultrasonic’s 71 — the Geek Bar wins on raw authenticity (80 vs 78) and a more complex dark-berry character. But the Lost Mary wins on smoothness (throat hit 48 vs 61) and has the spin-to-enhance dial for flavor customization. Pick the Geek Bar for intensity, the Lost Mary for comfort.
