Green furniture before buying two look

A look: whether the photocopy of the inspection report is affixed with the official seal The inspection report of the home improvement product is a prerequisite for entering the market. General merchants use copies at the time of sale, but they are not valid if they are not stamped with the red seal of the inspection agency. For inspection reports of inspection agencies in other provinces, it depends on the commissioned inspection or supervision and inspection. When entrusted with the inspection, the inspection agency is only responsible for the samples sent, and the degree of credibility is small. The supervisory inspection report is the result of the random sampling inspection of the same batch of products produced and sold by the quality supervision department and has certain authority. At present, most of the reports on counterfeit inspections have been altered, and none of the official seals for inspection or official seals of inspection agencies are counterfeit reports. In addition, the validity period of the test report is six months, and the test report that exceeds the validity period will lose its authenticity.

Purchase floor anti-four traps

Trap 3: The standard specification for non-standard panels that are used to impersonate the target floor should be 760mm x 125mm x 18mm, but some unscrupulous businesses will make great use of their specifications to make profits. The most common is to change the thickness of 18mm to 17mm or even thinner, so be sure to look carefully at the specifications when buying a floor. Don't buy unqualified flooring because it is cheap, so as to avoid problems in post-installation.

Trap #4: Stealing for boards Some merchants will earn high profits by stealing boards, changing boards, etc. For example, one or two boxes per floor will be removed, so that consumers will need to spend at least a few hundred dollars to make up for it. Consumers are advised to make a purchase after the purchase, and at the same time ask the merchant for an invoice and indicate the quantity and type of purchase on the invoice.

True or false "Yuba" identification has three parties

Selecting Yuba security is the most important assessment indicator. A truly qualified product is subject to rigorous testing. Consumers are often deceived because they cannot test their safety at the time of purchase. Here, teach consumers a few simple ways to test.

Method One: Inspecting the manufacturer's counterfeit products, the manufacturer's address is very ambiguous, there is no registered trademark, and there is no "R" sign for the formal registered trademark. In addition, it can be seen from the manufacturer's after-sales service and advertising that the manufacturers are regular. Counterfeit goods often have vague promises but no after-sales service.

Method 2: Inspecting the appearance of products The appearance and packaging of counterfeit goods are often rough. However, the production conditions of formal products are very demanding. For example, heating lamps must be strictly waterproof and explosion proof. The manufacturing process is complicated and the detection methods are strict. If even the appearance of the product and the appearance of the packaging are rough, the quality of Yuba is difficult to guarantee.

Method 3: Checking the price of the product The normal selling price of Yuba should be a few hundred dollars or more, and go up according to the change of function. Below this range, the above two considerations should be combined.
