Test Report Nicotine salt liquids explained (IQOS III)
Nicotine salt liquids advice for Scotland, covering test report, what to look for and where the trade-offs actually sit.
There is no single best nicotine salt liquids for everyone in Scotland, and anyone telling you otherwise is selling something. The 4.0 ml capacity is a genuinely useful middle ground: enough liquid for a long session without turning the device into a pocket problem.
Anyone who has compared nicotine salt liquids options in Scotland quickly learns that specification lists only tell part of the story. The Ocean Teal finish hides fingerprints far better than the gloss options, which matters more than it sounds on a device handled daily.
We would pair the RELX Pro with a 50:50 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.
The narrow bore mouthpiece is comfortable over long sessions and resists the condensation that gathers on narrower tips. Comparing this against a 50:50 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume. The 4.0 ml capacity is a genuinely useful middle ground: enough liquid for a long session without turning the device into a pocket problem.
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.
Two things to check before ordering: the USB-C socket on the base and whether the 1.4 Ω mesh coil is the newer generation. Battery behaviour is where the RELX Pro earns its keep: the 1000 mAh cell holds a usable charge for most of a day at 90 and recharges over USB-C. We would pair the RELX Pro with a 50:50 PG/VG liquid, which is where the balance between throat hit and cloud density sits most comfortably.

Flavour and performance notes
A representative profile is Kiwi Lime: tangy, green, described as tart kiwi balanced by lime. On a 50:50 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 USB-C are both in stock before committing, and check that the magnetic contact matches your existing device if you already own hardware. Duty and GBP rates move, so treat prices as current rather than fixed.
