The pod style devices are cheaper than the older style cloud chuckers and most of those now are refillable and not the juul style ones. I'm seeing good ones for $30-$50. The non removable battery gives them less longevity although they're still significantly more environmentally friendly than disposables. I used a fog machine to quit smoking and I've kept using them, but I definitely get why new vapers are largely going with the USB sticks now.
