Servicing Flavour variety packs explained

Flavour variety packs advice for Liverpool, covering servicing, what to look for and where the trade-offs actually sit.

Finding the right flavour variety packs in Liverpool is easier than most catalogues make it sound. The included spare coils are useful for the first fortnight, after which you will be ordering your own.

The gap between a mid-range and a premium flavour variety packs narrows once you know which components you actually use. The 8.0 ml capacity is a genuinely useful middle ground: enough liquid for a long session without turning the device into a pocket problem.

Replacement coils are widely available, and the 0.2 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 0.2 Ω dual mesh coil changes the draw character compared with the 50:50 PG/VG liquid sitting in the chamber.

Comparing this against a 50:50 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume. The 8.0 ml capacity is a genuinely useful middle ground: enough liquid for a long session without turning the device into a pocket problem. Expect roughly 500 full puffs from a charge at 12 mg/ml, based on average session length in our testing.

Build quality is the quiet differentiator here, with tight seams and a connector that has not loosened after repeated removal. The Stealth Grey 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.

Pricing in Liverpool shifts with import duty, so the figures here reflect current GBP rates rather than a fixed list price. Airflow control on the RELX 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 50, and pushing beyond that adds heat rather than anything worth carrying.

In Liverpool, availability of the 0.2 Ω dual mesh coil is the practical bottleneck, not the device itself. The wide bore mouthpiece is comfortable over long sessions and resists the condensation that gathers on narrower tips. Comparing this against a 50:50 PG/VG setup shows the difference clearly: one favours flavour, the other favours volume.

Charging over Micro-USB takes about 84 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 0.2 Ω dual mesh coil is the newer generation. For cloud chasers, the learning curve is shorter than the specification list suggests, and daily use is straightforward from the first charge.

Specifications

Every unit in the RELX Pro family shares the same core platform, so the differences come down to the numbers below.

Flavour and performance notes

A representative profile is Blue Raspberry Frost: sweet, tangy, described as sharp blue raspberry with a long cold finish. On a 50:50 PG/VG ratio this reads clearly on the first day and holds its character to roughly the 0.2 Ω dual mesh mark before the coil begins to mute it.

Practical considerations in Liverpool

Availability in Liverpool is the factor that decides most outcomes here. Confirm the 0.2 Ω dual mesh and the Micro-USB are both in stock before committing, and check that the 510-X matches your existing device if you already own hardware. Duty and GBP rates move, so treat prices as current rather than fixed.

Our advice is to order one, use it for a fortnight, and only then decide whether to stock up.
