How we pick

chi-fi is a shortlist, not a database. Here is what goes into a pick and what does not.

Where picks come from

Each gadget is chosen by reading published reviews and measurements, comparing specifications, and following what owners say in community discussions. A product makes the list when those sources broadly agree it is good for the money.

What we do not do

  • We do not test the gadgets ourselves. Every page is research summarised, never a personal review.
  • We do not give scores or star ratings. A number would suggest a measurement we have not made.
  • We do not show live prices. Prices are rounded “from” prices in US dollars. The AliExpress price depends on the seller, version, shipping and coupons.

What a product page tells you

  • A one-line gist of what the gadget is.
  • The “from” price.
  • Pros and cons in plain language, including the trade-offs.
  • A short description with the main specifications.
  • A link to buy it on AliExpress.

Budget

The budget control on the home page and the category pages dims every pick priced above the amount you choose, so you can see what fits at $25, $50 or $100.

Buy links are affiliate links, so chi-fi may earn a commission when you buy, at no extra cost to you. A pick with no working buy link is kept off the shelves. See About for more.
