Crystal Galaxy Focus 2 Refill Pack Mr Blue/Mad Blue: what you are buying

Crystal Galaxy Focus 2 Refill Pack Mr Blue/Mad Blue is the Mr Blue/Mad Blue option in the Crystal Galaxy Focus 2 Refill Pack range, priced at £7.99 and rated at 30,000 puffs. We list what the product actually is rather than padding it with specifications we cannot verify.

The full Crystal Prime range is at Crystal Prime, and this line alone runs to 31 flavours. Everything we ship is genuine UK-compliant stock.

Is Mr Blue/Mad 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/Mad 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.

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

Ordering, delivery and the legal bit

Sales are strictly 18+ and every order is age-checked before it ships. Nicotine is highly addictive, which is worth stating plainly.

Browse all pods and refills, or head to the sale if price is the deciding factor. If you are unsure whether this fits your device, check the listing details before ordering.

Getting the best from each pod

A UK prefilled pod holds no more than 2ml, so any high puff rating describes the system over its life, not a single pod.

  • Let a fresh pod sit for a minute after clicking it in so the wick saturates.
  • Store spares upright and out of direct heat to reduce the chance of leaking.
  • A muted or scorched taste is the usual sign a pod is spent.
  • Keep pods out of reach of children and recycle them responsibly rather than binning them loose.

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

Choosing your nicotine strength

This prefilled pod 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.

If you are unsure, most adults switching from a pack a day start at the higher end and drop down later. 10mg options and 20mg options are browsable separately if you want to compare.

What the multibuy actually saves you

The offer on this line is buy 3 for £22. At £7.99 each, 3 would normally be £23.97, so the bundle saves £1.97 and works out at £7.33 apiece.

That also clears our £20.00 threshold, so UK delivery is included. Mix and match across flavours is allowed, which is the sensible way to use it.

Baskets above £20 ship free within the UK. Weekday orders placed before 4pm go out the same day.

Other flavours in the Crystal Galaxy Focus 2 Refill Pack range

The same product comes in a spread of profiles, so there is usually a closer match. 31 flavours sit under this name, including:

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

Where this sits in the Crystal Prime range

A single product tells you little; the shape of the range tells you a lot. We stock 255 Crystal Prime products, running from £2.59 to £12.99. 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 Crystal Prime page. Other Crystal Prime 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

Judging a product in isolation is how people end up disappointed. We list 1,412 products in this category, and 29 in the same puff class. 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.
  • Bottled e-liquid works out cheaper per millilitre if you are willing to refill rather than swap.

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.

At £7.99 for a rated 30,000 puffs, that is roughly 0.27p per 1,000 puffs. That number is only as good as the rating behind it, and every brand measures generously.

  • The buy 3 for £22 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/Mad Blue against the rest of the line

Same product, different flavour, is the fairest comparison available. There are 31 options under this name:

Buying two from different families and alternating stops either going flat on you. The buy 3 for £22 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 you buy small bottles often rather than one large one.

The single-use disposable ban reshaped the rest. 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.

Everything we sell is UK-compliant stock bought through UK distribution. This is an 18+ product and orders are verified before dispatch.

Delivery, returns and buying with confidence

The buying side is straightforward. Weekday orders placed before 4pm are dispatched the same day, and UK delivery is free once your basket reaches £20.00. Delivery choices, including tracked services, appear at checkout.

Opened consumables are not returnable, which is standard for the category. Anything faulty or wrongly sent is our problem to fix, not yours. Sales are strictly 18+ and every order is age-verified before dispatch.

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

Looking after it, and what goes wrong

A short list of habits prevents nearly every common problem.

  • Prime before the first draw. Click the pod in and leave it a minute. Drawing on a dry wick is what causes that scorched first hit.
  • 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.

Buying this as a first purchase

New to this format? Three decisions cover almost everything.

  1. Format. A prefilled pod is the no-mess option. Bottled e-liquid costs less per millilitre if you do not mind refilling.
  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/Mad 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.

Nicotine strength, explained properly

Of every decision on this page, strength is the one worth thinking hardest about. 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.

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.

The sensation itself is part of the decision. 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

Nearly everyone who vapes daily ends up running two or three flavours rather than one, and there is a reason for it. 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 3 for £22 offer exists precisely for this, and it can be mixed across flavours rather than spent on one.

The terminology, in plain English

Product listings in this category lean on shorthand, so here is what the common terms actually mean.

  • A pod kit or starter kit pairs a rechargeable battery device with pods, and charges over a standard USB cable.

None of it is complicated once the words are unpicked, and knowing them makes comparing two products far quicker.

Pros & cons

Pros

  • Zero-mess flavour change — snap in, done
  • Consistent draw from a factory-primed coil
  • Long shelf-life, easy to travel with

Cons

  • Costs more per ml than freestanding e-liquid
  • Pods are proprietary to a specific device
  • Only sold at 20 mg or 10 mg — no lower strengths

Customer Buying Tips

  • Check device compatibility: a pod must match your exact device family (e.g. "Elfa Pro" pods only fit Elfa Pro devices).
  • Store sealed pods upright, below 30 °C — heat and sunlight drain flavour.
  • Rotate flavours: using the same pod flavour back-to-back dulls your palate within a week.
  • Prime the pod for 60 seconds after fitting to avoid a dry hit.

Frequently asked questions

Is there a multibuy on this?

Yes, the offer is buy 3 for £22, and it can be mixed across qualifying flavours rather than being limited to this one.

What nicotine strengths does it come in?

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

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.

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.

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.

How many puffs does the Crystal Galaxy Focus 2 Refill Pack Mr Blue/Mad Blue give?

It is rated at 30,000 puffs by the manufacturer, measured under lab conditions. Real world use depends on how hard and how often you draw, so treat it as a comparison figure between products rather than a promise.

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.
