How to choose a swimming ring?

Summer is a great time for teenagers to embrace nature and stretch nature. The least of which is the Swimming Ring.

The selection skills of the swimming rings are as follows:
1. Reject "Three None" products and recognize the 3C certification logo. When purchasing a children's swimming circle, first see if the swimming circle indicates whether the manufacturer, manufacturer's address, contact information, production date, shelf life and other information, and whether there are 3C certification signs. The 3C logo is generally affixed to the product surface, or the product is pressed on the product. If you look closely, you will find that multiple small diamond -shaped "CCC" secret records. There is a random code behind each 3C logo, and each random code has corresponding manufacturers and products. When the certification signing management center is issued a compulsory product certification mark, it has entered the corresponding product into a computer database, and consumers can use the National Quality Certification Center for encoding and query.
2. Choose a swimming ring with smoothness, thick material, and clear contrast between the color and the water surface; the soft, elastic swimming ring should be selected on the fabric, so that it has a cushioning effect when it collides, and avoids children's harm.
3. When buying a swimming ring, you can choose a product of multiple airbags and have a separate inflatable mouth, so that even if one of the airbags leaks, you can have enough air to support swimmers.
4. If there is a pungent odor in the swimming ring, it may be made of inferior plastic, which contains chemical composition that is harmful to the human body.
