How we test Nicotine salt liquids in Scotland (2026) (v3)
Nicotine salt liquids advice for Scotland, covering handling, what to look for and where the trade-offs actually sit.
Budget matters in Scotland, but with nicotine salt liquids the cheapest option is rarely the one that lasts. The instruction booklet is thin, but the diagrams are clear enough that most people set the device up without further help.
Budget matters in Scotland, but with nicotine salt liquids the cheapest option is rarely the one that lasts. 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.
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. Build quality is the quiet differentiator here, with tight seams and a connector that has not loosened after repeated removal. Charging over USB-C takes about 42 from empty, and the pass-through means the device can be used while plugged in on the smaller batteries.
For budget shoppers, the learning curve is shorter than the specification list suggests, and daily use is straightforward from the first charge. 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. The throat hit is noticeably firmer than a 65:35 PG/VG blend, so if you prefer a smoother draw, mix accordingly.
We would pair the RELX Pro with a 65:35 PG/VG liquid, which is where the balance between throat hit and cloud density sits most comfortably. Replacement coils are widely available, and the 0.8 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.
Flavour tracking stays consistent from the first day to roughly the 0.8 Ω mesh mark before the profile flattens and a swap makes sense. What surprised us most was how little the 0.8 Ω mesh coil changes the draw character compared with the 65:35 PG/VG liquid sitting in the chamber. The Forest Green 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 Vanilla Custard: creamy, rich, described as warm vanilla bean with a smooth cream finish. On a 65:35 PG/VG ratio this reads clearly on the first day and holds its character to roughly the 0.8 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 0.8 Ω mesh and the USB-C are both in stock before committing, and check that the 510 thread matches your existing device if you already own hardware. Duty and GBP rates move, so treat prices as current rather than fixed.
If any of the above addresses what you were trying to solve, the rest of the pages in this section cover it in more detail.
