If the product has a problem, the merchant has to charge. Recently, Mr. Wu, a citizen, has broken his mind.

Warranty period no door at the beginning of last year, Mr. Wu, who lives in Jiang'an District, spent more than 5,000 yuan to buy a bed, a wardrobe and two bedside tables, the warranty period is two years. Last month, Mr. Wu found that the drawer of a bedside table was not flexible and the slide was a bit awkward. Recently, when the drawer was pulled halfway, it was stuck. He found the receipt at the time of purchase and contacted the merchant. The merchant said that the two-year warranty covers only the sheet itself. The wearing parts such as handles and slides are not covered by the warranty, and only new replacements can be purchased. "Fortunately, it is a small piece, and the price is not expensive." After many rounds of negotiations, Mr. Wu had to replace a new slide. "I don't understand, it is obviously part of the furniture. If something goes wrong, it will not be considered." Recently, the reporter visited the Jiangcheng furniture market and found that all merchants stated that “man-made damage†is not included in the after-sales free warranty, but there is no explanation for what is “man-made damageâ€. The salesperson of a wardrobe store even said: "After the maintenance master went to the door, it will be clearly divided." "The door fee" becomes the warranty condition. The warranty period of Wuchang a solid wood furniture is one year. The reporter checked the brand's warranty regulations and found that Scratches and smudges on the furniture are not covered by the warranty; although there is no need to pay during the warranty period, the door-to-door fee is charged.

A salesperson told reporters that the installation process has a great impact on the quality of the floor. Only the manufacturer can be installed to enjoy the warranty service.

The installation fee is 35 yuan / square meter. A person in charge of a furniture company reminded that there is no specific warranty specification for furniture and building materials. Consumers should purchase furniture and building materials in regular stores and sign a standard purchase contract, requiring merchants to produce relevant certificates and warranty cards for the goods. It is also necessary to specify the warranty period and warranty coverage on the invoice so that there is evidence to follow when defending the rights.
Chloride Ion Sensor
The water quality Fluoride Ion Sensor is an instrument used to detect the concentration of fluoride ions in water. The water quality fluoride ion sensor has high sensitivity and can quickly and accurately detect the concentration of trace fluoride ions in water. This has important implications for monitoring the safety of water sources and sanitary indicators of water quality. The sensor adopts advanced sensing technology, which can provide high-precision measurement results and monitor the changes of fluoride ion concentration in water in real time, and give timely feedback to users. The fluoride ion sensor is small in size, easy to operate and easy to use. Users only need to immerse the sensor in water to obtain the data of fluoride ion concentration in water. At present, fluoride ion sensors are mainly used in environmental monitoring, monitoring of fluoride ion concentration in natural water bodies, groundwater, drinking water, fluoride ion concentration in industrial production wastewater, agricultural irrigation, scientific research and other occasions. Our company also provides matching fluoride ion controllers, which can realize more abundant display, control, recording and other functions.
