In my opinion, cost-effective products are usually more prominent in the following areas： 1. Electronic products： -Some mid-range mobile phones (such as some models of Xiaomi, realme and other brands) -Some headphones in audio products (such as Anker, KZ and other brands) -Some cheap but powerful smart watches and bracelets 2. Household goods： -Some basic furniture from IKEA -Some daily necessities of MUJI -Cost-effective kitchen appliances (such as rice cookers, air fryers, etc.) 3. Daily consumer goods： -Some basic products in domestic skin care products -Some cheap but good quality clothing brands However, what is "cost-effective" depends to a large extent on personal needs, usage habits and budget. A truly cost-effective product should be a product with a reasonable price and a long service life under the premise of meeting your actual needs. It is easy to misunderstand that the cheapest is the most cost-effective. In fact, durability and practicality are often more important.
