How to judge which water cups are good products?

It is convenient and quick for everyone to communicate on the Internet, but there are also some troubles. It's not like in a physical store, you can touch it with your hands if you see it with your own eyes. Communicating on the Internet can only understand products through visual pictures, videos, texts, etc., and then judge whether the products are good or bad through consumer evaluations, which will inevitably cause everyone to be somewhat subjective when shopping. After receiving some products, it is not clear how to judge whether they are good or bad, or if there are problems such as returning and exchanging goods, they should pay attention to using them.

Today, the editor will share with friends how to judge which of the water glasses (stainless steel water cups and plastic water cups) that have just been bought are bad.

1. look

When you receive a newly purchased water cup, check first to see if the packaging is damaged, if the water cup is damaged, if there are any accessories missing, if the pattern is printed incompletely, if the paint surface is worn, if there are obvious impurities in the material, etc. Seeing is a very demanding step. After seeing the problem, judge the seriousness of the problem, whether it affects the use of the product, etc., so that you can make a reasonable decision on the newly purchased water bottle.

2. Smell

Smell the smell, is there a pungent smell, is there a mildew smell, is there a smell that shouldn't appear. Friends can understand the first two points, whether there is a taste that should not appear. I believe that many friends will have doubts, what is the smell that should not appear, that is, this water glass is re-sold after being used by others. I have met friends who told me that the water glasses they bought had obvious dairy taste. If the water glasses you bought have the obvious taste of other drinks, most of the time these water glasses have been used by others.

3. Touch

Touching is very important to judge the workmanship of the water cup. I believe that most of my friends do not understand the water cup factory process, including what standards the water cup should meet after production. Sometimes it is not possible to find out all the problems by looking, but touching can make people feel more intuitively. By touching the water glass, you can clearly feel whether there is deformation in the water glass, whether the water glass has obvious sharp edges, and whether there are obvious impurity particles on the sprayed surface of the water glass.

4. Try out

After looking, smelling and touching, no problems were found.Then we have to try it out. Trying it out is not using it. You can not clean the water cup first. Pour in clear water at the specified temperature, which must be at the specified temperature. Because some plastic water cups cannot withstand high temperature, the thermos cup must be boiling water. Close the lid tightly and place it upside down for 15 minutes to observe whether the water cup is sealed or leaks.

Please note that when you pick up the thermos cup, you should feel the temperature of the outer wall of the water cup. Whether there is an obvious temperature rise before the hot water is filled, it means that the heat preservation function of the water cup is defective.
