RELX devices maintenance guide (8.0 ml)
RELX devices advice for Trinidad, covering throat hit, 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. The standard bore mouthpiece is comfortable over long sessions and resists the condensation that gathers on narrower tips.
Anyone who has compared relx devices options in Trinidad quickly learns that specification lists only tell part of the story. Flavour tracking stays consistent from the first day to roughly the 1.2 Ω mesh mark before the profile flattens and a swap makes sense.
For value hunters, 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 55:45 PG/VG blend, so if you prefer a smoother draw, mix accordingly.
The 5.0 ml capacity is a genuinely useful middle ground: enough liquid for a long session without turning the device into a pocket problem. Expect roughly 938 full puffs from a charge at 10 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.
Pricing in Trinidad shifts with import duty, so the figures here reflect current TTD rates rather than a fixed list price. Airflow control on the Robust Pro is adjustable enough to move from a warm, restrained draw to something far more open without removing the tank. Vapour production is more than adequate at 25, and pushing beyond that adds heat rather than anything worth carrying.
Charging over Micro-USB takes about 53 from empty, and the pass-through means the device can be used while plugged in on the smaller batteries. Two things to check before ordering: the Micro-USB socket on the base and whether the 1.2 Ω mesh coil is the newer generation. Battery behaviour is where the Robust Pro earns its keep: the 5000 mAh cell holds a usable charge for most of a day at 25 and recharges over Micro-USB.
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 55:45 PG/VG liquid sitting in the chamber. The Midnight Black finish hides fingerprints far better than the gloss options, which matters more than it sounds on a device handled daily.
The standard bore mouthpiece is comfortable over long sessions and resists the condensation that gathers on narrower tips. Comparing this against a 55:45 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume. The 5.0 ml capacity is a genuinely useful middle ground: enough liquid for a long session without turning the device into a pocket problem.

Flavour and performance notes
A representative profile is Pineapple Ice Cream: creamy, sweet, described as dairy-style pineapple dessert. On a 55:45 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.
