I'm on day 5 of this thing. Been hitting like a champ. Now It's starting to get clogged, and the liquid is pulling to the mouth piece. If I hit it hard, it'll flood, but if I go nice and slow, it doesn't flood. This Cart works better than any I've used. It works on all my batteries, even the Godzilla! I'll be ordering more since they're way cheaper than the Vision Clearomizer.
