RELX devices maintenance guide (3.5 ml) (v3)
RELX devices advice for Trinidad, covering inhaling technique, what to look for and where the trade-offs actually sit.
Anyone who has compared relx devices options in Trinidad quickly learns that specification lists only tell part of the story. The build quality on Uwell Calibre 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.
The gap between a mid-range and a premium relx devices narrows once you know which components you actually use. The 6.5 ml capacity is a genuinely useful middle ground: enough liquid for a long session without turning the device into a pocket problem.
In Trinidad, availability of the 1.2 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 70:30 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume.
What surprised us most was how little the 1.2 Ω mesh coil changes the draw character compared with the 70:30 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. Worth noting that the magnetic contact takes a small amount of care to keep clean, which we cover in the maintenance section below.
The throat hit is noticeably firmer than a 70:30 PG/VG blend, so if you prefer a smoother draw, mix accordingly. 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 70:30 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume.
Replacement coils are widely available, and the 1.2 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. What surprised us most was how little the 1.2 Ω mesh coil changes the draw character compared with the 70:30 PG/VG liquid sitting in the chamber.

Flavour and performance notes
A representative profile is Blueberry Muffin: creamy, sweet, described as baked blueberry with a soft crumb. On a 70:30 PG/VG ratio this reads clearly on the first day and holds its character to roughly the 1.2 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 1.2 Ω mesh and the Micro-USB are both in stock before committing, and check that the magnetic contact matches your existing device if you already own hardware. Duty and TTD rates move, so treat prices as current rather than fixed.
Availability shifts often, so check the current listing before committing to a large order.
