Why do many people who smoke cigarettes switch to electronic cigarettes? Which e-cigarette brand is better?

I used to be my best friend and smoked cigarettes, but now I smoke e-cigarettes. E-cigarettes do have many advantages over traditional cigarettes. For example, we all know that cigarettes will produce tar after burning, and the lungs of people who smoke for many years will turn black, and e-cigarettes have no tar. For our own health, we can't smoke any more. Then, if you smoke, you will always have a choking smell. My family and colleagues were very angry, so I changed the e-cigarette of MOTI Magic Flute, and the restoration degree was good.
