I Love my Donuts pen. 3 things though.. I’ve found that loading it with the same size dab of shatter I would have done if I were using a rig could clog up the air holes that are a little more than halfway up the atomizer walls, so I am sure to only load it with smaller amounts (usually less than what was shown in the video). Also, when cleaning, if using isopropyl, DO NOT soak overnight in the iso, as it will strip the paint (or whatever the pen is coated with).. rather… soak for a very short time then clean off asap. Finally… DO NOT remove the ‘pin’ from the charger, (the little metal circle in the center of the threaded charging ‘port’) as a vital electrical wire is soldered to the end of it. I found out the hard way after a clog that resulted in me believing something was wrong with the battery or charger, which caused me to have to order another charger. Love my Donuts pen, though… IMO it’s pretty much the best pen in the Kandypens lineup as i’m not a fan of combustion and would rather have clean vapor.
