If you put it in the cupboard, it is inconvenient to switch it on and off every time. In fact, if it is always on, it will automatically heat up when the temperature is below the threshold. It is acceptable if the thermal insulation performance is good. I'm afraid it's a waste to buy one with poor insulation effect.

I wanted to buy a new person last weekend and visit Suning. If I had bought a big water heater and brought a small kitchen treasure, it would have been much cheaper, but now I just want to buy it by myself, and I don't think it is appropriate. Besides, it will occupy valuable cabinet space. And it is mainly used to wash dishes. Before washing dishes, it won't be slower than the kitchen treasure and it's very cheap, so I decided not to buy it.
