Nicotine salt liquids head to head for experienced users (IQOS III)

Nicotine salt liquids advice for Scotland, covering head to head, what to look for and where the trade-offs actually sit.

We spent weeks putting nicotine salt liquids options through their paces so the recommendations here reflect real use. The instruction booklet is thin, but the diagrams are clear enough that most people set the device up without further help.

The throat hit is noticeably firmer than a 55:45 PG/VG blend, so if you prefer a smoother draw, mix accordingly. Pricing in Scotland shifts with import duty, so the figures here reflect current GBP rates rather than a fixed list price. Airflow control on the RELX Pro is adjustable enough to move from a warm, restrained draw to something far more open without removing the tank.

Flavour tracking stays consistent from the first day to roughly the 1.4 Ω mesh mark before the profile flattens and a swap makes sense. In Scotland, availability of the 1.4 Ω mesh coil is the practical bottleneck, not the device itself. The narrow bore mouthpiece is comfortable over long sessions and resists the condensation that gathers on narrower tips.

Comparing this against a 55:45 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume. The 2.5 ml capacity is a genuinely useful middle ground: enough liquid for a long session without turning the device into a pocket problem. Expect roughly 1649 full puffs from a charge at 10 mg/ml, based on average session length in our testing.

We would pair the RELX Pro with a 55:45 PG/VG liquid, which is where the balance between throat hit and cloud density sits most comfortably. Replacement coils are widely available, and the 1.4 Ω mesh coil is the sensible default to keep in stock. The included spare coils are useful for the first fortnight, after which you will be ordering your own.

Delivery across Scotland is typically two to four working days with tracked dispatch, and returns are straightforward within the standard window. The build quality on RELX Pro is a step above most of what sits in the same price bracket, and the finish resists the chipping that usually shows after a few months of pocket carry. Comparing this against a 55:45 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume.

If you take one thing from this page, make it the coil compatibility check. A device that needs a coil you cannot source locally becomes an expensive ornament within a month. What surprised us most was how little the 1.4 Ω mesh coil changes the draw character compared with the 55:45 PG/VG liquid sitting in the chamber. The Lilac Mist finish hides fingerprints far better than the gloss options, which matters more than it sounds on a device handled daily.

Flavour and performance notes

A representative profile is Frozen Berry Sorbet: sweet, icy, described as cold berry inhale with a soft exhale. On a 55:45 PG/VG ratio this reads clearly on the first day and holds its character to roughly the 1.4 Ω mesh mark before the coil begins to mute it.

Practical considerations in Scotland

Availability in Scotland is the factor that decides most outcomes here. Confirm the 1.4 Ω mesh and the Micro-USB are both in stock before committing, and check that the Q-Plus matches your existing device if you already own hardware. Duty and GBP rates move, so treat prices as current rather than fixed.
