Evidence before a recommendation.
01
Use primary sources. Model details come from manufacturer manuals or support pages.
02
Separate facts from checks. A seller’s photos and claims still need your own review.
03
Refresh anything that moves. Prices, availability, shipping, and return terms belong to the current listing.
Before you click “Buy”
Keep the decision in your hands.
Compare multiple listings. Read the exact condition and return terms. Pay on the marketplace, and save the listing description.
