Try one of these units with a carb cap, you can lower temps like a mofo to the point that it's vaping so slowly that you usually wouldn't even get a hit. But they you carb it and add a bunch of air restriction and to match the rate at which your dab is vaping, and get a fat hit. Example, she could be running it a lot lower though
