You need to heat it up somehow dude. I had the same issue.. Have you asked them for advice? They’ll answer if you do.

I held it in front of a heater for like 20 secs...a hairdryer would work too.

Exactly the people hating are noobs a simple pre heat pen stops this issue

I had the same issue but had no idea wtf I was doing with it.
Didnt know it needed to be heated at right temp etc etc but it was a freebie from another vendor as a bonus he swears by them thats all he smokes these days also.
Vendor just said keep puffing on it till you get smoke he never told me about it exploding if it gets to hot lol
Bits flying around the room lol
I would listen to some advice on these comments from others that know about about these vape things how they work etc.
Do not be discouraged they do need to be at right temp shame.
I was not told this too till boooom lol
Running out of breath to I was pulling on it like a donkey lol

I had the same problem but as soon as I heated it up it was fine. I just put it under my pillow for 15 mins but a hair dryer or leaving it by the radiator will work too. This vendor has outstanding service if you message them they will help you out in no time

Same happened to me last night, been using carts for ages and was super careful with the voltage as these were new to me. Cool went at 2.8 volts and I was huffing smoke. Tried to unscrew this morning to salvage and the glass cracked.

Shane as the flavour was decent for the shirt time it actually worked.
