Unresponsive button?.
Funny you should mention that as I had that problem the 1st time I tried to use it.
I fully charged the batteries in a charger and then I put them in the vaporizer and when I clicked the button 3 times nothing happened. I tried this a few times and nothing happened.
I even went on YouTube to make sure I was doing it right
I tried other 3500mAh batteries and still it wouldn’t switch on.
I was gonna email the company I bought it from to say It’s faulty but before I done that I plugged in the charge cable and the light around the button flashed and it worked fine after that.
