Several principles for choosing a campus card-swiping water boiler:

Brand

Choose a big brand of water boiler to save a lot of trouble. All aspects of quality are guaranteed.

Trademark

Check the trademark of the water boiler. If the trademark is blocked or altered, it means it is a fake product.

Health License

Water boilers belong to the health industry and must have a health license, otherwise they are illegal.

After-sales service

After-sales service is a key factor in product reputation. If the after-sales service is not done well, it means that the company has no strength.
