Experienced Users guide to RELX devices (reviewed) (8.0 ml)
RELX devices advice for Trinidad, covering first device, what to look for and where the trade-offs actually sit.
Local availability in Trinidad shapes the practical answer more than the marketing does. Airflow control on the Uwell Calibre is adjustable enough to move from a warm, restrained draw to something far more open without removing the tank.
The gap between a mid-range and a premium relx devices narrows once you know which components you actually use. Build quality is the quiet differentiator here, with tight seams and a connector that has not loosened after repeated removal.
What surprised us most was how little the 0.6 Ω mesh coil changes the draw character compared with the 65:35 PG/VG liquid sitting in the chamber. The Arctic White finish hides fingerprints far better than the gloss options, which matters more than it sounds on a device handled daily. Worth noting that the 510-X takes a small amount of care to keep clean, which we cover in the maintenance section below.
The wide bore mouthpiece is comfortable over long sessions and resists the condensation that gathers on narrower tips. Comparing this against a 65:35 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.
Vapour production is more than adequate at 100, and pushing beyond that adds heat rather than anything worth carrying. Materials are unremarkable on paper and feel reassuringly solid in the hand, with no flex in the body at all. The instruction booklet is thin, but the diagrams are clear enough that most people set the device up without further help.
We would pair the Uwell Calibre 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 0.6 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.
In Trinidad, availability of the 0.6 Ω mesh coil is the practical bottleneck, not the device itself. Pricing in Trinidad shifts with import duty, so the figures here reflect current TTD rates rather than a fixed list price. Comparing this against a 65:35 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume.

Flavour and performance notes
A representative profile is Frozen Berry Sorbet: sweet, icy, described as cold berry inhale with a soft exhale. On a 65:35 PG/VG ratio this reads clearly on the first day and holds its character to roughly the 0.6 Ω mesh mark before the coil begins to mute it.
Practical considerations in Trinidad
Availability in Trinidad is the factor that decides most outcomes here. Confirm the 0.6 Ω mesh and the Type-C fast charge are both in stock before committing, and check that the 510-X matches your existing device if you already own hardware. Duty and TTD rates move, so treat prices as current rather than fixed.
