How to judge whether the quality of the electric heating tube you bought is qualified

　　Shopping is psychologically prepared, and I don’t know what the quality of this thing I bought is and whether it is durable or not. I feel the same way when buying a heating pipe. The electric heating pipe is a metal shell from the surface, so you can’t tell its quality from the surface.
