Choosing RELX devices: long-session users edition (Robust Pro)
RELX devices advice for Trinidad, covering maintenance routine, what to look for and where the trade-offs actually sit.
The gap between a mid-range and a premium relx devices narrows once you know which components you actually use. Materials are unremarkable on paper and feel reassuringly solid in the hand, with no flex in the body at all.
Finding the right relx devices in Trinidad is easier than most catalogues make it sound. Replacement coils are widely available, and the 0.8 Ω regular coil is the sensible default to keep in stock.
The silicone tip 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. The 2.5 ml capacity is a genuinely useful middle ground: enough liquid for a long session without turning the device into a pocket problem.
The instruction booklet is thin, but the diagrams are clear enough that most people set the device up without further help. Flavour tracking stays consistent from the first day to roughly the 0.8 Ω regular mark before the profile flattens and a swap makes sense. In Trinidad, availability of the 0.8 Ω regular coil is the practical bottleneck, not the device itself.
We would pair the RELX Pro with a 70:30 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 regular 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.
Battery behaviour is where the RELX Pro earns its keep: the 1000 mAh cell holds a usable charge for most of a day at 80 and recharges over USB-C. Expect roughly 1724 full puffs from a charge at 10 mg/ml, based on average session length in our testing. Replacement coils are widely available, and the 0.8 Ω regular coil is the sensible default to keep in stock.
What surprised us most was how little the 0.8 Ω regular coil changes the draw character compared with the 70:30 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 thread takes a small amount of care to keep clean, which we cover in the maintenance section below.
Two things to check before ordering: the USB-C socket on the base and whether the 0.8 Ω regular coil is the newer generation. Vapour production is more than adequate at 80, and pushing beyond that adds heat rather than anything worth carrying. We would pair the RELX Pro with a 70:30 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 Raspberry Lemonade: sweet, tart, described as summer lemonade with a raspberry accent. On a 70:30 PG/VG ratio this reads clearly on the first day and holds its character to roughly the 0.8 Ω regular 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 0.8 Ω regular 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 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.
