RELX devices maintenance guide (Classic Menthol)

RELX devices advice for Trinidad, covering pricing, what to look for and where the trade-offs actually sit.

Budget matters in Trinidad, but with relx devices the cheapest option is rarely the one that lasts. 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.

There is no single best relx devices for everyone in Trinidad, and anyone telling you otherwise is selling something. Delivery across Trinidad is typically two to four working days with tracked dispatch, and returns are straightforward within the standard window.

Replacement coils are widely available, and the 0.15 Ω dual 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 0.15 Ω dual mesh coil changes the draw character compared with the 20:80 PG/VG liquid sitting in the chamber.

Build quality is the quiet differentiator here, with tight seams and a connector that has not loosened after repeated removal. The Cobalt Blue 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 1.6 ml capacity is a genuinely useful middle ground: enough liquid for a long session without turning the device into a pocket problem. Expect roughly 854 full puffs from a charge at 20 mg/ml, based on average session length in our testing. Delivery across Trinidad is typically two to four working days with tracked dispatch, and returns are straightforward within the standard window.

Vapour production is more than adequate at 150, 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. Delivery across Trinidad is typically two to four working days with tracked dispatch, and returns are straightforward within the standard window.

Two things to check before ordering: the USB-C socket on the base and whether the 0.15 Ω dual mesh coil is the newer generation. Battery behaviour is where the Uwell Calibre earns its keep: the 3000 mAh cell holds a usable charge for most of a day at 150 and recharges over USB-C. We would pair the Uwell Calibre with a 20:80 PG/VG liquid, which is where the balance between throat hit and cloud density sits most comfortably.

Comparing this against a 20:80 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume. The instruction booklet is thin, but the diagrams are clear enough that most people set the device up without further help. The included spare coils are useful for the first fortnight, after which you will be ordering your own.

Specifications

Here is what the engineering actually delivers, without the marketing language.

Flavour and performance notes

A representative profile is Vanilla Custard: creamy, rich, described as warm vanilla bean with a smooth cream finish. On a 20:80 PG/VG ratio this reads clearly on the first day and holds its character to roughly the 0.15 Ω dual 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 0.15 Ω dual 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 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.
