I'm iold and don't care for change so I wouldn't have bought this 3,000 mg disposable green Crack pen under normal circumstances but my neighborhood dispensary had it on sale for $21 and change. You definitely don't want pull real hard because you will cough like crazy. I wouldn't recommend carrying it in your pocket because your pocket lint will clog it, making you pull harder and harder to clear the clog and will inevitably loose an eye watering , deep coughing fit. .q I should figure out how to properly clean it. I can't say it's too good to be true but it is hit or miss, pun intended. You do need to store it carefully or constantly clean out the tip but it's got 3 freaking grams of oil in it so even if I'd paid msrp, about twice what I paid it would still be a hell of a deal. I've been trying out different pens/Carts for a decade. This one doesn't have much flavor, almost neutral, to be honest., and it isn't very smooth but I would absolutely recommend having one in your arsenal of herb and oils intake methods. I've had. This thing 2 weeks and it's still mostly full. Great deal if not an every day pensive I'd put the oil in a just above acceptable range compared to carts and even legal state disposables. But every old 0othead knows, there will always come a time when you've run out of herb/oil. So having this enormous reservoir of cheap but vapable oil around for rainy days just makes sense.
