Sources and checks

We use official manufacturer documents for features, availability and launch prices. We link the specific documents and record when they were checked. An old launch price is not a current store quote.

Buying judgment

We explain what changes for an existing owner and for a first-time buyer. We say when a conclusion depends on final price, warranty, condition or the reader's needs.

Limits

When we have not physically tested a product, we say so clearly. We do not turn a specification table into claims about measured performance, photographs or real-world battery life. Material changes update the article's revision date.
