Elux Legend Nic Salt E-Liquid Mr Blue: what you are buying

Elux Legend Nic Salt E-Liquid Mr Blue is the Mr Blue option in the Elux Legend Nic Salt E-Liquid range, priced at £2.89. Everything on this page comes from the listing itself, so nothing is guessed at.

The full Elux range is at Elux, and this line alone runs to 56 flavours. Stock is genuine and bought through UK distribution.

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.

Choosing your nicotine strength

This e-liquid is listed in 5mg and 10mg and 20mg. UK law caps nicotine at 20mg per ml, so that is the strongest you will find anywhere.

  • 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.
  • 5mg suits light users or anyone stepping down gradually.

Going too low often means vaping more to compensate, which defeats the point. 10mg options and 20mg options are browsable separately if you want to compare.

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 5 for £10. At £2.89 each, 5 would normally be £14.45, so the bundle saves £4.45 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.

Is Mr Blue the right pick for you?

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

  • If you want an all-day vape, a less sugary 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.

Nobody gets every flavour right first time, which is why the multibuys exist.

Other flavours in the Elux Legend Nic Salt E-Liquid range

Sticking with the line you already like is easier than starting from scratch elsewhere. 56 flavours sit under this name, including:

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

Where this sits in the Elux range

A single product tells you little; the shape of the range tells you a lot. We stock 148 Elux products, running from £2.89 to £8.99. 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 Elux page. Other Elux products worth a look:

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

Price alone is a poor guide, so it helps to see the field. We list 736 products in this category. At £2.89, 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.

No puff rating is published for this listing, so we will not invent a per-puff figure.

  • 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

The quickest way to judge a flavour is against its own siblings, not against the whole shop. There are 56 options under this name:

Palate fatigue is real: rotating two profiles keeps both tasting sharper for longer. The buy 5 for £10 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 no retailer here sells a 50ml bottle of 20mg salt.

The end of single-use disposables changed what sits on the shelf. 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.

Buying this as a first purchase

First time buying this sort of product? The decisions that matter are simpler than the shelf suggests.

  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 5mg and 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.

Get those three right and the rest is detail. The deals page is the cheapest way to try more than one at a time.

Or stay with the brand: all Elux products, 116 in total. Sticking to a brand you already know is the least risky way to try something different.

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.

We cannot resell an opened consumable, so opened items are outside the returns policy. If something arrives faulty or incorrect, contact us and we will sort it. Age verification applies to every order, and unverified orders are refunded rather than sent.

Nicotine is an addictive substance and these products are intended for adults who already smoke or vape.

Looking after it, and what goes wrong

The faults people blame on a product are usually storage or priming.

  • 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.

Do those four things and most of the usual problems never appear.

More flavours in this line

The rest of the line, if you want to compare before choosing.

Most regulars run two flavours in rotation rather than one.

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.

The fix costs nothing. 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.

Within this line alone there are options to pair with:

The buy 5 for £10 offer exists precisely for this, and it can be mixed across flavours rather than spent on one.

Where Elux fits in the wider market

Not all vape brands do the same job, even when they sit on the same shelf. We list 148 Elux products, which puts it among the largest ranges we carry. The complete list is on the Elux page.

A large range is not automatically better. What it does give you is somewhere to go when you want a change without gambling on an unfamiliar name. Brands that make both hardware and liquid tend to design them to work together, which is why pods from one family rarely fit another. Brands that only make liquid put their effort into flavour development instead, and often outperform the hardware houses on taste alone.

The takeaway is straightforward. Once you find a brand whose profiles suit your palate, its other lines are a far safer bet than a random product at the same price. That is worth more than it sounds in a category where you cannot try before you buy. The full category runs to 736 products if you would rather compare across brands than within 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

Is there a multibuy on this?

Yes, the offer is buy 5 for £10, and it can be mixed across qualifying flavours rather than being limited to this one.

Do I have to be 18 to buy this?

Yes. Sales are strictly 18+ and every order is age-verified. Orders that cannot be verified are refunded rather than sent.

When will my order arrive?

Weekday orders placed before 4pm are dispatched the same day. UK delivery is free once your basket passes £20, and paid options are shown at checkout.

What does Mr Blue 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.

What if I do not like the flavour?

Flavour is personal and we cannot resell an opened consumable, so the multibuys are the low risk way to try more than one. Buying a pair from different families is the usual approach.

What nicotine strengths does it come in?

It is listed in 5mg and 10mg and 20mg. UK law caps nicotine at 20mg per ml, so that is the strongest available from any retailer.

How should I store it?

Upright, out of direct sunlight and away from heat. Warmth thins liquid and dulls flavour, and a hot car is the most common cause of a leak.
