Mike, I'm sorry you had this experience. We will send you a fresh pack of 5 mega carts. We are looking into this matter further. If you still had the cart, we would have liked you to send it to us for inspection. A WOW or CoolCart holds 1ml of liquid, which is ~ 20-25 drops. A mega cart holds 5ml, which is ~ 100 drops. We believe the cart was too dry to function properly.
You can PM or email me at email@example.com with your mailing info so I can get this out today.
