What do I need to pay attention to when buying a cup? What to pay attention to when buying a cup onl

1. Pay attention to the water storage capacity of the water cup. Some cups are opaque or have two layers. So it may not be as much water storage as it appears on the surface. Read the instructions for yourself.

2. Pay attention to the scope of use of the water cup: I bought a cup before and it was actually used to heat milk in the microwave. Depending on the range of use, the maximum temperature it can withstand is also different. It is recommended that the maximum temperature of drinking water must be higher than 100 degrees Celsius.

3. Pay attention to the precautions: for example, it is strictly forbidden to put it in the microwave oven, it is strictly forbidden to fall and press, whether you can put food, etc.

4. Pay attention to the thermal insulation effect when buying a water cup, especially for sports cups, cycling, etc., these thermal insulation requirements will be higher, and this thermal insulation performance must be carefully looked.

5. If you use it for the first time and don't use it for a long time, you must remember to wash it again. Some cups have a filter screen, and the filter screen is easy to have impurities and needs to be cleaned regularly.

6. In general, some plastic cups will have a layer of scale after a long time, and at this time, you can also consider replacing them while paying attention to cleaning. Or use some glasses, ceramic cups, stainless steel, etc. Judging from the experience of using it in the past few years, I personally prefer to use stainless steel cups.

When buying a cup, you need to pay attention to it, I think the main thing is the function of the cup, as well as the appearance of the cup, whether the cup is easy to wash, and the main use of the cup to choose a large cup or a small cup, and the appearance of the cup, there are some formal places, and the requirements for the cup are relatively high.
