How we evaluate

01
We define what actually decides the purchase for your situation (home size, capacity, voltage, budget).
02
We check the listing specs against the manufacturer manual.
03
We compare prices in your market with a 24-hour timestamp.
04
We publish the verdict, pros, cons and who it is not for — including when it is not worth it.

Editorial rules

We never write “we tested” or “we used” without actually testing the product.
Marketplace prices only appear with the date and time of the check, refreshed every 24 hours.
Only sellers with a warranty that holds in the reader’s country are listed.
A third-party rating, when it exists, is attributed to its source and never presented as ours.
Every guide has an author, a date and a change log.
