with the cart and atomizer being one unit, it sounds doubtful, but no idea. Would have to have one in-hand to know for sure. Of course, there are always alternate ways (ie: might be able to drill a small hole in cart and fill with syringe and then plug hole with hot glue).outwest, do you think the cartridges can be refilled???
But admit it, you've danced to it at least once in your life, haven't you?
