What should I pay attention to when buying a toilet water saver?

1, don't trust the advertisements and product descriptions of manufacturers and merchants. People with relevant knowledge should analyze whether these descriptions are scientific or even contrary to science. For example, everyone knows that "fire and water are incompatible". If a merchant describes the product as "the world's top high-tech product combining fire and water", it is absolutely deceptive. Of course, generally speaking, it is not so explicit, but similar examples are not uncommon: for example, a shower water-saving product called Magic Water Saver is claimed to be designed by "applying ultrasonic principle"-just use your head a little to know that you are talking nonsense: ultrasonic water has bullet-like penetration, can it be used in the shower! For another example, some products claim to adopt the technology of "vortex pressurization" and the principle of "variable diameter pressurization", but "vortex pressurization" and "variable diameter pressurization" can not only pressurize, but also decompress!

2. Collect and compare the product advertisements and promotional materials of merchants in different periods. If merchants use the same product in different principles, or even conflict with each other, or the product performance descriptions are too different, it means that the publicity is not true, and both the merchants and their products have problems. For example, the magical water-saving device mentioned above, the nonsense "supersonic principle", "jet technology" and "vortex technology" have "invented" dynamic water flow.

Don't trust certificates, media reports, "recommendations from authoritative organizations" and so on-it is very easy to forge in the IT era! China has the largest number of certification types and certification institutions in the world, and the proliferation of counterfeit goods may be the most serious in the world!

Don't trust patented technology and patented products. Patented technology is not equal to advanced technology, and patented products are not equal to high-quality products. On the contrary, if a product introduces little performance and principle, and deliberately emphasizes the use of "patented technology", it is necessary to be vigilant. In addition, patents include invention patents, utility model patents and design patents, among which design patents have nothing to do with the technical content of products, but only with the packaging materials and packaging methods of goods, that is, they have nothing to do with the use value of products. If you are in doubt about the patent, you can download the patent documents from China National Intellectual Property Administration website for analysis (this information can only be obtained online after the patent is granted for a period of time).

5. It is very important for dealers and group users not to buy products that infringe patent rights and trademark rights-selling and using infringing products should also be liable for compensation.

In short, for individual users, we should ask more questions (consult people with experience or relevant professional knowledge) and analyze more to see whether the product advertisements of the merchants are reasonable, fraudulent or suspected of fraud; For group users, we should first buy a small number of products for performance testing, and then buy them in bulk after recognizing the performance and effect.
