<br />
<br />Note: 
<br />
<br />1.If the heating wire is not red after you receiving the product or having charged, the reason is that our product design has switch lock. And the treatment is here, open/close the dial continuously and fast for 3 times;if the light flickers, it means the switch lock is on and you can ignite after then.
<br />
<br />2.The situation of lock-in: when igniting, heating wire is not red and charge light does not come on.
