Hello,

My Smoke unit (1.0) has stopped working. I charge it until it is green but even with a new cartridge doesn't produce smoke. I purchased this package 2 years ago. Do these things go bad after some time? Please advise.

Mine did the same thing. I have a very similar situation as you.

I bought new cartridges because I was told these expire. Even with brand new, recent cartridges, I get very little smoke if any. And you have to suck ("inhale") very hard to get this little smoke... Burns the back of your throat when doing this though.

I was never told the unit expires if placed in a drawer for 2 years... This could be the reason.

Thank you Sal. I will be looking for refills then.

Mine also did the same thing. I also got the new version and yep did it again. Mad as hell. But go to the store or look on Amazon you can get what goes into the pen. Way cheaper.
