Evidence before adjectives.
How we build and maintain the journal.
Primary sources first
Device records cite manufacturer pages. Statements about capacity, operating modes and components are attributed to the manufacturer and checked against the named model.
Separate observation from claims
We identify source-based descriptions. We do not present brand claims as independent measurements or claim testing that has not happened.
No promotional rankings
Directory order is organisational. Inclusion is not an endorsement. No sales rankings, purchase links, promotional prices or affiliate referrals are included.
Corrections and uncertainty
When regional versions differ, the difference should be preserved. A source date indicates when a page was checked, not a promise that it remains unchanged.
Health and age context
Nicotine is addictive. This site is for adult readers and is not medical advice. Device features do not establish reduced risk.
