Sumbee electric hot water bottles are commonly used by different people for different purposes. Here are some examples:

1. People with menstrual cramps: Women who suffer from menstrual cramps often find relief by placing the hot water bottle on their lower abdomen. The heat can help relieve pain and relax muscles.

2. People with pain or sore muscles: Sumee hot water bottle is often used as a natural remedy to relieve pain, muscle stiffness or cramps. The application of heat can help relax muscles, promote blood circulation and thus provide temporary relief.

3. People seeking warmth: The Sumbee hot water bottle is often used by people who want to keep warm during the colder months or in cool environments. They provide localised warmth and can be used while sitting on the couch or even outdoors.

4. Elderly: The Sumbee hot water bottle is popular with the elderly due to its convenience compared to a traditional hot water bottle or heat pad. The Sumbee hot water bottle provides warmth and comfort as they may have a lower tolerance to cold temperatures and a hot water bottle can help keep you cosy during colder times
