Check the nozzle: rubber hot water bag is the need to fill hot water first, and then use, in the purchase, check the nozzle is not strong, take a look at the rubber bonding is seamless, if there is a gap, it may leak from these places, that is trouble.
See if there is leakage: the plug of the rubber hot water bag is a spiral, and it is very tight after tightening. When you buy it, if it is not convenient to try to fill water, you can tighten the lid under the condition of filling air, and then gently press it to see whether there is gas out. If there is no leakage, it is also watertight.
Look at the elasticity: good rubber is very elastic and soft to touch. When buying rubber hot water bags, press the surface of the hot water bag by hand to see whether the elasticity is large. If it feels thick and soft and has strong elasticity, it is a good hot water bag.
Look at the color: If the hot water bottle is made of used rubber, it should be dull in color and look very old, while good rubber is bright and shiny. If the hot water bottle is beautiful and pure, it is made of good material.
Smell: Pick up a hot water bottle and put it under your nose and smell it. If it smells bad, it's bad. If it doesn't smell bad, it's just natural rubber, it's good.

Take a white paper towel or toilet paper and wipe the hot water bottle surface. If the paper is not contaminated, the material is good.
