Expert Verdict: Why I Recommend the Hayati Pro Ultra Plus 25000 

By Adam Collins, Lead Vaping Compliance & Product Specialist

In my seven years of testing and compliance auditing across the UK market, I’ve seen countless devices claim to be the "next big thing." Most are just rebranded disposables. However, when the Hayati Pro Ultra Plus 25000 hit my desk for compliance review, I knew immediately this was different.

This kit isn't just about the approx 25,000 puff headline; it’s about smart engineering designed to solve three major pain points for the modern vaper: legal compliance, flavour fatigue, and wasted hardware.

Here is my in-depth breakdown of why the Hayati Pro Ultra Plus 25000 isn't just a powerful vape, but a future-proof investment.

1. The Technical Deep Dive: TPD Compliance Solved

The first question every heavy vaper asks is: “How can approx 25,000 puffs be legal?”

On the product page, we give the quick answer. Here, I want to explain the genius behind the engineering that makes it compliant with UK TRPR regulations.

 

The Vacuum-Sealed Reserve System

The Hayati Pro Ultra Plus 25000 uses a three-part system that physically separates the large e-liquid reserve from the heating element.

• The TPD Chamber: The coil sits inside a small, dedicated 2ml chamber, this is the legal limit. This chamber is never exceeded.

• The Reserve Tanks: The massive 24 ml total capacity comes from two separate 10ml containers that feed the chamber.

• The Mechanism: E-liquid is drawn from the reserve tanks into the 2ml chamber through a vacuum-sealed, gravity-fed system as you vape. This ensures that only the legal amount of nicotine salt e-liquid is ever exposed to the coil at one time.

This design is technically sound, legally robust, and represents the best solution I have seen for delivering true high-capacity vaping under the current UK laws.

 

2. Flavour Consistency: The Dual Independent Mesh Coil Advantage

The biggest flaw in any high-puff disposable is flavour fade. Around the 3,000-puff mark, the flavour often dips because the coil has been running too long.

Hayati solved this, not just with better coils, but with Dual Independent Mesh Coils tied to the Twist-to-Switch System.

• Zero Contamination: Each of the two flavours has its own dedicated mesh coil. When you switch from 'Straw Guava' to 'Dragon Berries', you are physically switching the connection to a fresh, unused coil and tank.

• The Benefit: This means the flavour on puff 10,000 is often as clean and intense as it was on puff 100, because you've been distributing the wear and tear across two separate heating elements.

In my testing, this dual-coil structure is what truly elevates the Hayati above single-coil, high-puff competitors.

 

3. Value and Longevity: The Real Cost Per Puff

I often tell customers to ignore the upfront price and focus on the Cost Per Puff (CPP).

Device Comparison	Estimated Puffs	Retail Price	Calculated Cost Per Puff (CPP)
Hayati Pro Ultra Plus 25000	approx 25,000	£10.89	approx 0.00043p per puff
Lost Mary BM6000	approx 6,000	£11.49	approx 0.00192p per puff
Standard 600-Puff Disposable	approx 600	£4.50	approx 0.00750p per puff

 

The Takeaway: When you look at the economics, the Hayati Pro Ultra Plus 25000 pays for itself within the first week compared to buying disposables. It is the most wallet-friendly option on the market for a heavy daily vaper.

 

4. Advanced Usability: Features We Didn't Discuss

The product page mentions the Smart LED Screen, but it misses a few key usability features that make it ideal for daily carry:

• Airflow Management (The Draw): Hayati has tuned the airflow specifically for a tight, controlled Mouth-to-Lung (MTL) draw. This mimics the resistance of a cigarette far better than many airy pod kits, making it my #1 recommendation for ex-smokers.

• Rapid Type-C Charging: While the 850mAh battery provides a day or two of heavy use, the USB-C turbo charging capability gets the device back to full power in under an hour (approx 45-60 minutes). Minimal downtime is essential for an all-day device.

• "Ban-Proof" Future: With potential bans looming for traditional single-use devices, the Hayati Pro Ultra Plus 25000 is designed to last. It has a rechargeable battery and replaceable pods, ensuring it remains compliant and useful well into the future.

 

Adam's Final Recommendation

If you are currently a heavy disposable user (going through 2-3 per week) or you suffer from constant flavour fatigue, the Hayati Pro Ultra Plus 25000 is not just an upgrade, it's the responsible, cost-effective, and flavour-rich solution you need.

It's one of the few long-life devices on the market where the technical complexity truly serves the user experience.
