Living with it
What the maker’s own pages and manual say about owning this unit, and what owners report in public. Each line links to where it was read.

What independent testers found
We do not test units ourselves. These are figures and verdicts published by named testers, with the maker’s claim beside them where the tester gave it; where a tester relays owners’ reports rather than a measurement, the row says so.
