Please note:1. After injecting the electronic cigarette oil, wait for about a few minutes, and then suck, because the cotton inside needs to fully absorb the oil, otherwise there will be a burning smell.2. The electronic cigarette is caused by the heat of the heating wire to spray smoke oil, so it is sure to generate heat.3. There will be a problem that the coil is too hot if continuous burning for a long time.4. The lower the resistance, the faster the heating speed, this is a common problem in e-cigarettes.
