Sour box mod Coil in Bristol: the compare shortlist
Sour in Bristol: 15 units tested over 3 weeks, box mod formats, priced per 10 ml for Bristol.
How to tell a good box mod from a repack
We run sour the same way in Bristol: same box mod, same 3 days, same coil resistance. The only variable was the coil, and that turned out to be the thing buyers get wrong.
Ordering into Bristol usually means waiting 2–4 business days. Plan the reorder around that, not around the flavour you like best.
The short version: sour in Bristol works if the box mod, the coil and the strength are chosen as one system. Everything below is what we measured while doing exactly that.
What a sour box mod really costs in Bristol
Sour in a box mod is not the same product you see in a catalogue photo, and the price per 10 ml is where the gap shows. In Bristol the liquid, the coil and the power setting all have to agree before the flavour actually lands.
How we tested sour in a box mod
- Settle the draw first: mouth-to-lung or direct-to-lung, because it decides the coil and the liquid.
- Choose strength against the ceiling in the UK, which is 20 mg/mL for retail here.
- Order before 14:00 so the parcel leaves the same day and lands inside 2–4 business days.
- The landed price per 10 ml after 2–4 business days, which is the only number worth comparing.
- Returns window and who pays return postage when a box mod arrives sealed but wrong.
- Stock depth: 15 lines held, so the shortlist does not turn into a special order.
- The listed nicotine ceiling, which is 20 mg/mL in the UK, not a suggestion.
Where sour goes wrong
- Skipping the spare coil, which is the single part that decides how long sour in Bristol survives.
- Treating the advertised £63 entry kit as the real cost when refills run £3.15 per 10 ml.
- Ordering in bulk without checking whether couriers in Bristol accept nicotine freight.

Frequently asked questions
How long does sour in a box mod last?
In Bristol we measured 3 to 15 days per unit depending on the coil. The bottle outlasts the coil, so the coil is what you replace.
Why does sour taste burnt?
Almost always the coil, not the liquid. On the box mod units we ran, a coil past 6 days turned the sour blend itself harsh.
What nicotine strength should sour start at?
Start at whatever the UK allows on the label. If you already smoke, drop one step; if not, half of it for a box mod.
