Hayati Pro Max E-Liquid 100ml 50/50 Rainbow: what you are buying

Hayati Pro Max E-Liquid 100ml 50/50 Rainbow is the Rainbow option in the Hayati Pro Max E-Liquid 100ml 50/50 range, priced at £7.99. Everything on this page comes from the listing itself, so nothing is guessed at.

The full Hayati range is at Hayati, and this line alone runs to 20 flavours. We only list stock sourced through UK distributors.

Getting the best from the bottle

UK rules cap nicotine e-liquid at 10ml per bottle, so restocking is part of the routine.

  • Prime a fresh coil or pod before the first draw: fill it, then wait a few minutes so the wick soaks properly.
  • Store bottles upright, out of sunlight and away from heat, which keeps the flavour truer for longer.
  • A burnt taste usually means the wick has dried out rather than the liquid being at fault.
  • Keep bottles away from children and pets, and use the child-resistant cap as intended.

Small habits like priming and sensible storage do more for flavour than anything else.

Is Rainbow the right pick for you?

Names sell, but families predict. Work out which family you already enjoy and the choice gets easier. Rainbow is best judged against the other options in this line rather than in isolation.

  • If you want an all-day vape, a simpler profile usually lasts longer before palate fatigue sets in.
  • If you rotate flavours, pair this with something from a different family so your palate resets between them.
  • On cooling, this reads as an uncooled profile, which suits anyone who finds menthol overpowering.
  • If you are switching from cigarettes, strong sweet flavours can feel unfamiliar at first, and many adults settle after a week or two.

Most people land on a favourite after trying a handful, not on the first purchase.

Ordering, delivery and the legal bit

This is an 18+ product and age verification applies to every order. Nicotine is highly addictive, which is worth stating plainly.

Browse all e-liquids, or head to the sale if price is the deciding factor. Check your device takes this format before ordering, since pods are not universal.

What the multibuy actually saves you

The offer on this line is buy 2 for £14. At £7.99 each, 2 would normally be £15.98, so the bundle saves £1.98 and works out at £7.00 apiece.

That sits under the £20.00 free delivery threshold, so either add something small or take the offer twice. The offer applies across the qualifying range, not just this one flavour.

UK delivery is free once your basket passes £20. Weekday orders placed before 4pm go out the same day.

Other flavours in the Hayati Pro Max E-Liquid 100ml 50/50 range

If this one is not quite what you are after, the rest of the line is worth scanning. 20 flavours sit under this name, including:

A pair from different families tends to outlast a pair from the same one.

Choosing your nicotine strength

This e-liquid is listed in 0mg. The 20mg ceiling is a legal limit under UK rules, not a brand decision.

  • 0mg contains no nicotine and is chosen for the flavour and the ritual alone.

Start where you are comfortable rather than where you think you should be, and adjust from there. 10mg options and 20mg options are browsable separately if you want to compare.

Where this sits in the Hayati range

A single product tells you little; the shape of the range tells you a lot. We stock 721 Hayati products, running from £2.69 to £14.99. That breadth means you can usually stay inside the brand when you want a change, rather than starting over somewhere else.

The full lineup is on the Hayati page. Other Hayati products worth a look:

Staying within a brand you already rate is the low risk way to try something new.

How it compares to the rest of the category

Judging a product in isolation is how people end up disappointed. We list 736 products in this category. At £7.99, this one sits in the middle of the market.

  • Multibuy deals are where the price per unit drops hardest, and they can be mixed across flavours.
  • Reduced lines carry 1,558 products if the budget is the deciding factor.
  • Prefilled pods cost more per millilitre but remove the refilling entirely.

The honest answer is that most vapers end up owning two formats, not one.

The running cost, worked out

The useful figure is not the shelf price but the running cost once you settle into a rhythm.

We would rather leave the arithmetic blank than guess at a rating.

  • The buy 2 for £14 offer is the single biggest lever on that number.
  • Baskets over £20.00 ship free in the UK, so building to that threshold beats paying postage twice.
  • Nicotine strength changes consumption: many adults find a higher strength means reaching for the device less often.

Rainbow against the rest of the line

If this one is close but not quite right, its siblings are the obvious next step. There are 20 options under this name:

Most regulars keep two on the go rather than committing to one. The buy 2 for £14 offer makes that cheap to do.

Why the UK market looks like this

A lot of the format decisions here were made by law, not by marketing. UK rules cap nicotine at 20mg per ml, nicotine e-liquid bottles at 10ml, and prefilled pods and tanks at 2ml. That is why you buy small bottles often rather than one large one.

Since single-use devices were banned, the market moved to rechargeables. Rechargeable kits with replaceable pods took their place, which is why a device now comes with a charging port and a pod you swap rather than a sealed unit you bin. The upshot is less waste and a lower running cost, if you stick with one system.

We only list compliant stock sourced through UK distributors. Sales are 18+ and every order is age-checked.

Buying this as a first purchase

If this is your first order with us, a few things are worth knowing before you commit.

  1. Format. A bottle is the cheapest way to vape per millilitre, but you refill it yourself. Prefilled pods remove that job at a higher cost.
  2. Strength. This comes in 0mg. Heavier former smokers usually start high and step down.
  3. Flavour. You are looking at Rainbow. Pick a second from a different family so you have something to rotate to.

Beyond that, it is down to taste rather than technique. The deals page is the cheapest way to try more than one at a time.

Delivery, returns and buying with confidence

Here is what happens after you order. Weekday orders placed before 4pm are dispatched the same day, and UK delivery is free once your basket reaches £20.00. Tracked options are shown at checkout.

Opened consumables are not returnable, which is standard for the category. Faults and picking errors are resolved without argument. This is an 18+ purchase and orders are age-checked before they ship.

Nicotine is addictive. These products are for adult smokers and vapers.

Looking after it, and what goes wrong

A short list of habits prevents nearly every common problem.

  • Prime before the first draw. Fill, then wait a few minutes so the wick soaks fully. A dry first pull is what burns a coil.
  • Keep it cool and upright. Heat thins liquid and pushes it through seals, which is why a hot car is the usual cause of a leak.
  • Muted flavour is often you, not it. Palate fatigue is common on a single flavour, and rotating to a second profile resets it.
  • Store away from children and pets, and recycle spent hardware rather than binning it loose.

None of that is demanding, and it is the difference between a product that performs to the end and one that disappoints halfway.

Everything else that sits under this name.

Rotating a pair is the simplest fix for flavour fatigue.

Nicotine strength, explained properly

Strength is the decision people get wrong most often, and it is the one that most affects whether switching sticks. This listing offers 0mg. UK law caps nicotine at 20mg per ml, so nothing sold legally here goes higher, and the honest question is how far below that ceiling you should sit.

Going too low is the classic error. If a strength does not satisfy, you compensate by vaping more often, which costs more and rarely feels better. A heavier former smoker typically starts at the top of the range and steps down over weeks or months once the habit has settled. Someone who smoked lightly, or who has already been vaping a while, is usually comfortable in the middle.

There is a physical side to this as well. Higher strengths give a firmer hit at the back of the throat, which many people switching from cigarettes actively want, and which others find harsh. Nicotine salts are smoother than freebase at the same number, which is why bar-style liquids sit at 20mg without feeling like it. If you are unsure, buy one of each rather than committing to five of the wrong one. 10mg options and 20mg options are browsable separately.

Building a rotation instead of buying one thing

The single most common mistake is buying five of the same flavour. Palate fatigue sets in faster than people expect. A profile you loved on day one can taste flat by day ten, not because the product changed but because your palate stopped noticing it.

Rotation solves it entirely. Keep two profiles from genuinely different families on the go, and alternate between them. Something sweet paired with something sharp, or a fruit paired with a menthol, resets the palate each time you switch. Two flavours in rotation will each last noticeably longer than either would alone.

The same range gives you obvious partners:

The buy 2 for £14 offer exists precisely for this, and it can be mixed across flavours rather than spent on one.

Pros & cons

Pros

  • Best value per ml in the category
  • Choose your own device and coil
  • Available in a wide strength ladder

Cons

  • Refilling can leak if you overfill
  • Coil priming has a small learning curve
  • You handle the bottle — less discreet than pods

Customer Buying Tips

  • Match the strength to how much you smoked: 20+/day → 10-20 mg nic salt; 10/day → 10 mg; under 5/day → 3-6 mg freebase.
  • Match the ratio to your device: pod kits take 50/50, sub-ohm tanks take 70/30 shortfill.
  • Don't overfill: leaving the airhole clear prevents gurgling and leaking.
  • Shake before use so the nicotine and flavour integrate evenly.

Frequently asked questions

What nicotine strengths does it come in?

It is listed in 0mg. UK law caps nicotine at 20mg per ml, so that is the strongest available from any retailer.

Can I mix flavours in one order?

Yes. Multibuy offers apply across the qualifying range, so you can spread a bundle over several flavours instead of committing to one.

Is there a multibuy on this?

Yes, the offer is buy 2 for £14, and it can be mixed across qualifying flavours rather than being limited to this one.

Will this fit my device?

Check the listing details against your own kit before ordering. Pods are not interchangeable between brands, and even within a brand the families differ.

What does Rainbow actually taste like?

The listing name is the best guide we can give without inventing tasting notes. If you want a safer bet, pick a family you already enjoy.

Why is the puff rating so high when a pod only holds 2ml?

Because UK rules cap a prefilled pod at 2ml, a five-figure rating describes what the system delivers across the pods you use, not what sits in one pod.

Is it genuine stock?

Yes. Everything we list is sourced through UK distribution and is UK-compliant, including the 2ml pod, 10ml bottle and 20mg nicotine limits where they apply.
