Quality control is obviously bad. I'd pass.
Kept the lid off,  didn't keep in a humid environment,  didn't cough into it... Smoke was billowing out after a week of use.  Buy some activated carbon from a pet supply store,  it's in the aquarium care section.  Get a water bottle and some mesh filter.  Boom. Unlimited smoke buddies! Soak the carbon in 90% iso alcohol whenever it stops working,  and it's new again.  The smoke buddy prevents you from doing this,  therefore you have to shell out money twice a month.  Make it yourself!
