Crystal Pro Max Nic Salts by Hayati Mr Blue: what you are buying

Crystal Pro Max Nic Salts by Hayati Mr Blue is the Mr Blue option in the Crystal Pro Max Nic Salts by Hayati range, priced at £2.69. We list what the product actually is rather than padding it with specifications we cannot verify.

The full Hayati range is at Hayati, and this line alone runs to 57 flavours. Everything we ship is genuine UK-compliant stock.

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.

Treat the consumable well and it repays you in flavour consistency.

Ordering, delivery and the legal bit

This is an 18+ product and age verification applies to every order. Nicotine is addictive, and these products are for adults who already smoke or vape.

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 5 for £10. At £2.69 each, 5 would normally be £13.45, so the bundle saves £3.45 and works out at £2.00 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.

Spend over £20 and UK postage is included. Order before 4pm on a working day and it leaves us that afternoon.

Other flavours in the Crystal Pro Max Nic Salts by Hayati range

Sticking with the line you already like is easier than starting from scratch elsewhere. 57 flavours sit under this name, including:

• Cherry Ice
• Strawberry Raspberry Blueberry
• Fizzy Cherry
• Strawberry Watermelon Bubblegum

Buying two at once and alternating is the simplest way to stop any single flavour going flat on you.

Is Mr Blue the right pick for you?

Flavour is the hardest thing to buy blind, so it helps to think in families rather than names. Mr Blue is best judged against the other options in this line rather than in isolation.

• If you want an all-day vape, a more balanced 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.

Buying two or three at once is the cheapest way to find the one you keep coming back to.

Choosing your nicotine strength

This e-liquid is listed in 10mg and 20mg. The 20mg ceiling is a legal limit under UK rules, not a brand decision.

• 20mg gives the firmest throat hit and suits heavier former smokers, or anyone who finds lower strengths leave them vaping more often.
• 10mg is the common middle ground: enough to satisfy without the harshness some find at 20mg.

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

It is worth knowing what else the brand makes before you commit to one listing. 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:

• Hayati Pro Max Shisha Nic Salts Kiwi Orange Mint at £2.99
• Hayati Pro Max Plus Pods Watermelon Ice at £5.49
• Hayati Mini Ultra Pods Blue Razz Pineapple at £3.49
• Hayati Pro Max Plus Pods Blueberry Raspberry at £5.49

Brand loyalty in vaping is mostly about knowing what to expect, which counts for a lot.

How it compares to the rest of the category

The useful question is not what it costs, but what else that money buys. We list 736 products in this category. At £2.69, this one sits at the affordable end.

• 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.

None of those is objectively right. They suit different routines and different budgets.

The running cost, worked out

Work out cost per week and product comparisons get much easier.

Without a published rating there is no honest per-puff maths to show, so we leave it out.

• The buy 5 for £10 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.

Mr Blue against the rest of the line

If this one is close but not quite right, its siblings are the obvious next step. There are 57 options under this name:

• Cola Ice
• Cherry Ice
• Juicy Peach
• Blue Razz Lemonade
• Black Mamba
• Fizzy Cherry

Buying two from different families and alternating stops either going flat on you. The buy 5 for £10 offer makes that cheap to do.

Why the UK market looks like this

Some of what you see on the shelf is regulation rather than brand choice. UK rules cap nicotine at 20mg per ml, nicotine e-liquid bottles at 10ml, and prefilled pods and tanks at 2ml. That is why no retailer here sells a 50ml bottle of 20mg salt.

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. It also means the device outlives the flavour, which changes how you shop.

We only list compliant stock sourced through UK distributors. Age verification applies to every order without exception.

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.

These are small habits that pay back in flavour consistency.

More flavours in this line

Other options in the same range.

• Fresh mint
• Bru Ice
• Bubblegum Ice
• Mad Blue
• Cola Ice
• Strawberry Jelly Beans
• Strawberry Raspberry Ice
• Fizzy Cherry

Rotating a pair is the simplest fix for flavour fatigue.

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 10mg and 20mg. Heavier former smokers usually start high and step down.
3. Flavour. You are looking at Mr Blue. Pick a second from a different family so you have something to rotate to.

Everything else is preference rather than a decision that costs you money. The deals page is the cheapest way to try more than one at a time.

Delivery, returns and buying with confidence

Ordering is deliberately simple. Weekday orders placed before 4pm are dispatched the same day, and UK delivery is free once your basket reaches £20.00. You pick the service at checkout.

Opened consumables are not returnable, which is standard for the category. Faults and picking errors are resolved without argument. Age verification applies to every order, and unverified orders are refunded rather than sent.

Nicotine is highly addictive, and nothing here is intended for non-smokers.

What changed when disposables were banned

The shelf you are shopping from looks nothing like it did two years ago. Single-use disposable vapes were banned in the UK, and the market replaced them with rechargeable devices that take replaceable pods. The experience is deliberately similar: prefilled, no measuring, no mess. The difference is that the battery survives the flavour, so you replace a pod for a couple of pounds rather than the whole unit.

For most people the change was an improvement, financially and otherwise. A device bought once and fed with pods costs less over a month than a stream of sealed units, and produces far less waste. It also changed how you shop: the decision splits into hardware first, then consumables, rather than being one purchase repeated endlessly.

All stock here is compliant with the current UK framework. That means 2ml pods, 10ml nicotine bottles and a 20mg strength ceiling, with age verification on every order. Rechargeable kits and replacement pods are the two halves of that system if you are still assembling yours.

Nicotine strength, explained properly

More vapers give up on switching because of a bad strength choice than because of a bad flavour. This listing offers 10mg and 20mg. 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.

Most people reach for the lowest strength and end up vaping twice as much. 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.

Throat feel matters too. 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.
